We report cumulants of the proton multiplicity distribution from dedicated fixed-target Au+ Au collisions at s N N= 3.0 GeV, measured by the STAR experiment in the kinematic acceptance of rapidity (y) and transverse momentum (p T) within− 0.5< y< 0 and 0.4< p T< 2.0 GeV/c. In the most central 0%–5% collisions, a proton cumulant ratio is measured to be C 4/C 2=− 0.85±0.09 (stat)±0.82 (syst), which is 2 σ below the Poisson baseline with respect to both the statistical and systematic uncertainties. The hadronic transport UrQMD model reproduces our C 4/C 2 in the measured acceptance. Compared to higher energy results and the transport model calculations, the suppression in C 4/C 2 is consistent with fluctuations driven by baryon number conservation and indicates an energy regime dominated by hadronic interactions. These data imply that the QCD critical region, if created in heavy-ion collisions, could only …

The STAR collaboration presents jet substructure measurements related to both the momentum fraction and the opening angle within jets in p+ p and Au+ Au collisions at s N N= 200 GeV. The substructure observables include SoftDrop groomed momentum fraction (z g), groomed jet radius (R g), and subjet momentum fraction (z SJ) and opening angle (θ SJ). The latter observable is introduced for the first time. Fully corrected subjet measurements are presented for p+ p collisions and are compared to leading-order Monte Carlo models. The subjet θ SJ distributions reflect the jets leading opening angle and are utilized as a proxy for the resolution scale of the medium in Au+ Au collisions. We compare data from Au+ Au collisions to those from p+ p which are embedded in minimum-bias Au+ Au events in order to include the effects of detector smearing and the heavy-ion collision underlying event. The subjet …

We present high-precision measurements of elliptic, triangular, and quadrangular flow v 2, v 3, and v 4, respectively, at midrapidity for identified hadrons π, p, K, φ, K s, Λ as a function of centrality and transverse momentum in Au+ Au collisions at the center-of-mass energy s N N= 200 GeV. We observe similar v n trends between light and strange mesons which indicates that the heavier strange quarks flow as strongly as the lighter up and down quarks. The number-of-constituent-quark scaling for v 2, v 3, and v 4 is found to hold within statistical uncertainty for 0–10%, 10–40%, and 40–80% collision centrality intervals. The results are compared to several viscous hydrodynamic calculations with varying initial conditions, and could serve as an additional constraint to the development of hydrodynamic models.

We present systematic measurements of azimuthal anisotropy for strange and multistrange hadrons (K-s(0), Lambda, Xi and Omega) and phi mesons at midrapidity (vertical bar y vertical bar < 1.0) in collisions of U U nuclei at root S-NN = 193 GeV, recorded by the STAR detector at the Relativistic Heavy Ion Collider. Transverse momentum (p(T)) dependence of flow coefficients (v(2), v(3), and v(4)) is presented for minimum bias collisions and three different centrality intervals. Number of constituent quark scaling of the measured flow coefficients in U + U collisions is discussed. We also present the ratio of v(n) scaled by the participant eccentricity (epsilon(n){2}) to explore system size dependence and collectivity in U + U collisions. The magnitude of nu(2)/epsilon(2) is found to be smaller in U + U collisions than that in central Au + Au collisions contradicting naive eccentricity scaling. Furthermore, the ratios between …

The beam energy scan (BES) program at the BNL Relativistic Heavy Ion Collider (RHIC) was extended to energies below s N N= 7.7 GeV in 2015 by successful implementation of the fixed-target mode of operation in the STAR (Solenoidal Tracker At RHIC) experiment. In this mode, ions circulate in one ring of the collider and interact with a stationary target at the entrance of the STAR time projection chamber. The first results for Au+ Au collisions at s N N= 4.5 GeV are presented, demonstrating good performance of all the relevant detector subsystems in fixed-target mode. Results presented here include directed and elliptic flow of identified hadrons, and radii from pion femtoscopy. The latter, together with recent HADES results, reveal a long-sought peak structure that may be caused by the system evolving through a first-order phase transition from quark-gluon plasma to the hadronic phase. Directed and elliptic flow …

The B0 s and B+ production yields are measured in PbPb collisions at a center-of-mass energy per nucleon pair of 5.02 TeV. The data sample, collected with the CMS detector at the LHC, corresponds to an integrated luminosity of 1.7 nb-1. The mesons are reconstructed in the exclusive decay channels B0 s→ J/ψ (µ+ µ-) φ (K+K-) and B+→ J/ψ (µ+ µ-) K+, in the transverse momentum range 7–50 GeV/c and absolute rapidity 0–2.4. The B0 s meson is observed with a statistical significance in excess of five standard deviations for the first time in nucleus-nucleus collisions. The measurements are performed as functions of the transverse momentum of the B mesons and of the PbPb collision centrality. The ratio of production yields of B0 s and B+ is measured and compared to theoretical models that include quark recombination effects.

We report on the first measurement of charm-strange meson D s±production at midrapidity in Au+ Au collisions at s NN= 200 GeV from the STAR experiment. The yield ratio between strange (D s±) and nonstrange (D 0) open-charm mesons is presented and compared to model calculations. A significant enhancement, relative to a pythia simulation of p+ p collisions, is observed in the D s±/D 0 yield ratio in Au+ Au collisions over a large range of collision centralities. Model calculations incorporating abundant strange-quark production in the quark-gluon plasma and coalescence hadronization qualitatively reproduce the data. The transverse-momentum integrated yield ratio of D s±/D 0 at midrapidity is consistent with a prediction from a statistical hadronization model with the parameters constrained by the yields of light and strange hadrons measured at the same collision energy. These results suggest that the …

The STAR Collaboration reports measurements of the transverse single-spin asymmetry (TSSA) of inclusive π 0 at center-of-mass energies (s) of 200 GeV and 500 GeV in transversely polarized proton-proton collisions in the pseudo-rapidity region 2.7 to 4.0. The results at the two different energies show a continuous increase of the TSSA with Feynman-x, and, when compared to previous measurements, no dependence on s from 19.4 GeV to 500 GeV is found. To investigate the underlying physics leading to this large TSSA, different topologies have been studied. π 0 with no nearby particles tend to have a higher TSSA than inclusive π 0. The TSSA for inclusive electromagnetic jets, sensitive to the Sivers effect in the initial state, is substantially smaller, but shows the same behavior as the inclusive π 0 asymmetry as a function of Feynman-x. To investigate final-state effects, the Collins asymmetry of π 0 inside …

Nonmonotonic variation with collision energy (s NN) of the moments of the net-baryon number distribution in heavy-ion collisions, related to the correlation length and the susceptibilities of the system, is suggested as a signature for the quantum chromodynamics critical point. We report the first evidence of a nonmonotonic variation in the kurtosis times variance of the net-proton number (proxy for net-baryon number) distribution as a function of s NN with 3.1 σ significance for head-on (central) gold-on-gold (Au+ Au) collisions measured solenoidal tracker at Relativistic Heavy Ion Collider. Data in noncentral Au+ Au collisions and models of heavy-ion collisions without a critical point show a monotonic variation as a function of s NN.

Global hyperon polarization, PH, in Au+ Au collisions over a large range of collision energy, s NN, was recently measured and successfully reproduced by hydrodynamic and transport models with intense fluid vorticity of the quark-gluon plasma. While naïve extrapolation of data trends suggests a large PH as the collision energy is reduced, the behavior of PH at small s NN< 7.7 GeV is unknown. Operating the STAR experiment in fixed-target mode, we measured the polarization of Λ hyperons along the direction of global angular momentum in Au+ Au collisions at s NN= 3 GeV. The observation of substantial polarization of 4.91±0.81 (stat.)±0.15 (syst.)% in these collisions may require a reexamination of the viscosity of any fluid created in the collision, of the thermalization timescale of rotational modes, and of hadronic mechanisms to produce global polarization.

The effects of neutron skin on the multiplicity (N ch) and eccentricity (ϵ 2) in relativistic 44 96 Ru+ 44 96 Ru and 40 96 Zr+ 40 96 Zr collisions at s NN= 200 GeV are investigated with the Trento model. It is found that the Ru+ Ru/Zr+ Zr ratios of the N ch distributions and ϵ 2 in mid-central collisions are exquisitely sensitive to the neutron skin type (skin vs. halo). The state-of-the-art calculations by energy density functional theory (DFT) favor the halo-type neutron skin and can soon be confronted by experimental data. It is demonstrated that the halo-type density can serve as a good surrogate for the DFT density, and thus can be efficiently employed to probe nuclear deformities by using elliptic flow data in central collisions. We provide hereby a proof-of-principle venue to simultaneously determine the neutron skin type, thickness, and nuclear deformity.

In relativistic heavy-ion collisions, a global spin polarization, P H, of Λ and Λhyperons along the direction of the system angular momentum was discovered and measured across a broad range of collision energies and demonstrated a trend of increasing P H with decreasing s N N. A splitting between Λ and Λpolarization may be possible due to their different magnetic moments in a late-stage magnetic field sustained by the quark-gluon plasma which is formed in the collision. The results presented in this study find no significant splitting at the collision energies of s N N= 19.6 and 27 GeV in the BNL Relativistic Heavy Ion Collisions Beam Energy Scan Phase II using the STAR detector, with an upper limit of P Λ− P Λ< 0.24% and P Λ− P Λ< 0.35%, respectively, at a 95% confidence level. We derive an upper limit on the naive extraction of the late-stage magnetic field of B< 9.4× 10 12 T and B< 1.4× 10 13 T at s N N= 19 …

Measurements of the second Fourier harmonic coefficient (v 2) of the azimuthal distributions of prompt and nonprompt D 0 mesons produced in p p and p Pb collisions are presented. Nonprompt D 0 mesons come from beauty hadron decays. The data samples are collected by the CMS experiment at nucleon-nucleon center-of-mass energies of 13 and 8.16 TeV, respectively. In high multiplicity p p collisions, v 2 signals for prompt charm hadrons are reported for the first time, and are found to be comparable to those for light-flavor hadron species over a transverse momentum (p T) range of 2–6 GeV. Compared at similar event multiplicities, the prompt D 0 meson v 2 values in p p and p Pb collisions are similar in magnitude. The v 2 values for open beauty hadrons are extracted for the first time via nonprompt D 0 mesons in p Pb collisions. For p T in the range of 2–5 GeV, the results suggest that v 2 for nonprompt D 0 …

The STAR collaboration reports a measurement of the transverse single-spin asymmetries, A N, for neutral pions produced in polarized proton collisions with protons (p p), with aluminum nuclei (p Al) and with gold nuclei (p Au) at a nucleon-nucleon center-of-mass energy of 200 GeV. Neutral pions are observed in the forward direction relative to the transversely polarized proton beam, in the pseudorapidity region 2.7< η< 3.8. Results are presented for π 0 s observed in the STAR forward meson spectrometer electromagnetic calorimeter in narrow Feynman x (x F) and transverse momentum (p T) bins, spanning the range 0.17< x F< 0.81 and 1.7< p T< 6.0 GeV/c. For fixed x F< 0.47, the asymmetries are found to rise with increasing transverse momentum. For larger x F, the asymmetry flattens or falls as p T increases. Parametrizing the ratio r (A)≡ A N (p A)/A N (p p)= A P over the kinematic range, the ratio r (A) is found …

According to first-principle lattice QCD calculations, the transition from quark-gluon plasma to hadronic matter is a smooth crossover in the region μ B≤ T c. In this range the ratio, C 6/C 2, of net-baryon distributions are predicted to be negative. In this Letter, we report the first measurement of the midrapidity net-proton C 6/C 2 from 27, 54.4, and 200 GeV Au+ Au collisions at the Relativistic Heavy Ion Collider (RHIC). The dependence on collision centrality and kinematic acceptance in (p T, y) are analyzed. While for 27 and 54.4 GeV collisions the C 6/C 2 values are close to zero within uncertainties, it is observed that for 200 GeV collisions, the C 6/C 2 ratio becomes progressively negative from peripheral to central collisions. Transport model calculations without critical dynamics predict mostly positive values except for the most central collisions within uncertainties. These observations seem to favor a smooth …

We report a systematic measurement of cumulants, C n, for net-proton, proton, and antiproton multiplicity distributions, and correlation functions, κ n, for proton and antiproton multiplicity distributions up to the fourth order in Au+ Au collisions at s N N= 7.7, 11.5, 14.5, 19.6, 27, 39, 54.4, 62.4, and 200 GeV. The C n and κ n are presented as a function of collision energy, centrality and kinematic acceptance in rapidity, y, and transverse momentum, p T. The data were taken during the first phase of the Beam Energy Scan (BES) program (2010–2017) at the BNL Relativistic Heavy Ion Collider (RHIC) facility. The measurements are carried out at midrapidity (| y|< 0.5) and transverse momentum 0.4< p T< 2.0 GeV/c, using the STAR detector at RHIC. We observe a nonmonotonic energy dependence (s N N= 7.7–62.4 GeV) of the net-proton C 4/C 2 with the significance of 3.1 σ for the 0–5% central Au+ Au collisions. This is …

Dihadron azimuthal correlations containing a high transverse momentum () trigger particle are sensitive to the properties of the nuclear medium created at RHIC through the strong interactions occurring between the traversing parton and the medium, ie jet-quenching. Previous measurements revealed a strong modification to dihadron azimuthal correlations in Au+ Au collisions with respect to p+p and d+ Au collisions. The modification increases with the collision centrality, suggesting a path-length or energy density dependence to the jet-quenching effect. This paper reports STAR measurements of dihadron azimuthal correlations in mid-central (20%-60%) Au+ Au collisions at GeV as a function of the trigger particle's azimuthal angle relative to the event plane, . The azimuthal correlation is studied as a function of both the trigger and associated particle . The subtractions of the combinatorial background and anisotropic flow …

We present the first inclusive measurements of the invariant and softdrop jet mass in proton-proton collisions at s= 200 GeV at STAR. The measurements are fully corrected for detector effects, and reported differentially in both the jet transverse momentum and jet radius parameter. We compare the measurements to established leading-order Monte Carlo event generators and find that STAR-tuned pythia-6 reproduces the data, while LHC tunes of pythia-8 and herwig-7 do not agree with the data, providing further constraints on parameter tuning. Finally, we observe that softdrop grooming, for which the contribution of wide-angle nonperturbative radiation is suppressed, shifts the jet mass distributions into closer agreement with the partonic jet mass as determined by both pythia-8 and a next-to-leading-logarithmic accuracy perturbative QCD calculation. These measurements complement recent LHC measurements in …

Event-by-event long-range correlations of azimuthal anisotropy Fourier coefficients (v n) in 8.16 TeV p Pb data, collected by the CMS experiment at the CERN Large Hadron Collider, are extracted using a subevent four-particle cumulant technique applied to very low multiplicity events. Each combination of four charged particles is selected from either two, three, or four distinct subevent regions of a pseudorapidity range from− 2.4 to 2.4 of the CMS tracker, and with transverse momentum between 0.3 and 3.0 GeV. Using the subevent cumulant technique, correlations between v n of different orders are measured as functions of particle multiplicity and compared to the standard cumulant method without subevents over a wide event multiplicity range. At high multiplicities, the v 2 and v 3 coefficients exhibit an anticorrelation; this behavior is observed consistently using various methods. The v 2 and v 4 correlation strength …

The measurements reveal a large fourth-order angular modulation of cos 4 Δ ϕ=(16.8±2.5)% and smooth invariant mass distribution absent of vector mesons (ϕ, ω, and ρ) at the experimental limit of≤ 0.2% of the observed yields. The differential cross section as a function of e+ e− pair transverse momentum P⊥ peaks at low value with⟨ P⊥ 2⟩= 38.1±0.9 MeV and displays a significant centrality dependence. These features are consistent with QED calculations for the collision of linearly polarized photons quantized from the extremely strong electromagnetic fields generated by the highly charged Au nuclei at ultrarelativistic speed. The experimental results have implications for …

Background: The chiral magnetic effect (CME) is extensively studied in heavy-ion collisions at the BNL Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC). An azimuthal correlator called R Ψ m was proposed to measure the CME. By observing the same R Ψ 2 and R Ψ 3 (convex) distributions from A Multi-Phase Transport (ampt) model, by contrasting data and model as well as large and small systems and by event shape engineering (ESE), a recent preprint (arXiv: 2006.04251 v1) from STAR suggests that the R Ψ m observable is sensitive to the CME signal and relatively insensitive to backgrounds, and their Au+ Au data are inconsistent with known background contributions.Purpose: We examine those claims by studying the robustness of the R Ψ m observable using ampt as well as toy model simulations. We compare R Ψ m to the more widely used Δ γ azimuthal correlator to identify their …

An observable sensitive to the chiral magnetic wave (CMW) is the charge asymmetry dependence of the π− and π+ anisotropic flow difference, Δνn(Ach). We show that, due to non-flow correlations, the flow measurements by the Q-cumulant method using all charged particles as reference introduce a trivial linear term to Δνn(Ach). The trivial slope contribution to the triangle flow difference Δν3(Ach) can be negative if the non-flow is dominated by back-to-back pairs. This can explain the observed negative Δν3(Ach) slope in the preliminary STAR data. We further find that the non-flow correlations give rise to additional backgrounds to the slope of Δν2(Ach) from the competition among different pion sources and from the larger multiplicity dilution to π+ (π−) at positive (negative) Ach.

Abstract Isobaric 44 96 Ru+ 44 96 Ru and 40 96 Zr+ 40 96 Zr collisions at Image 1 GeV have been conducted at the Relativistic Heavy Ion Collider to circumvent the large flow-induced background in searching for the chiral magnetic effect (cme), predicted by the topological feature of quantum chromodynamics (QCD). Considering that the background in isobar collisions is approximately twice that in Au+ Au collisions (due to the smaller multiplicity) and the cme signal is approximately half (due to the weaker magnetic field), we caution that the cme may not be detectable with the collected isobar data statistics, within∼ 2σ significance, if the axial charge per entropy density (n 5/s) and the QCD vacuum transition probability are system independent. This expectation is generally verified by the Anomalous-Viscous Fluid Dynamics (avfd) model. While our estimate provides an approximate “experimental” baseline …

Flow harmonics (v n) of the Fourier expansion for the azimuthal distributions of hadrons are commonly employed to quantify the azimuthal anisotropy of particle production relative to the collision symmetry planes. While lower order Fourier coefficients (v 2 and v 3) are more directly related to the corresponding eccentricities of the initial state, the higher-order flow harmonics (v n> 3) can be induced by a mode-coupled response to the lower-order anisotropies, in addition to a linear response to the same-order anisotropies. These higher-order flow harmonics and their linear and mode-coupled contributions can be used to more precisely constrain the initial conditions and the transport properties of the medium in theoretical models. The multiparticle azimuthal cumulant method is used to measure the linear and mode-coupled contributions in the higher-order anisotropic flow, the mode-coupled response coefficients …

The charged particle pairs produced in the reaction pp→ p′+ h+ h−+ p′ are reconstructed from the tracks in the central detector and identified using the specific energy loss and the time of flight method, while the forward-scattered protons are measured in the Roman Pot system. Exclusivity of the event is guaranteed by requiring the transverse momentum balance of all four final-state particles. Differential cross sections are measured as functions of observables related to the central hadronic final state and to the forward-scattered protons. They are measured in a fiducial region corresponding to the acceptance of the STAR detector and determined by the central particles’ transverse momenta and pseudorapidities as well as by the …

We report systematic measurements of bulk properties of the system created in Au+ Au collisions at s N N= 14.5 GeV recorded by the STAR detector at the Relativistic Heavy Ion Collider (RHIC). The transverse momentum spectra of π±, K±, and p (p) are studied at midrapidity (| y|< 0.1) for nine centrality intervals. The centrality, transverse momentum (p T), and pseudorapidity (η) dependence of inclusive charged particle elliptic flow (v 2), and rapidity-odd charged particles directed flow (v 1) results near midrapidity are also presented. These measurements are compared with the published results from Au+ Au collisions at other energies, and from Pb+ Pb collisions at s N N= 2.76 TeV. The results at s N N= 14.5 GeV show similar behavior as established at other energies and fit well in the energy dependence trend. These results are important as the 14.5-GeV energy fills the gap in μ B, which is of the order of 100 MeV …

Within the ultrarelativistic quantum molecular dynamics model, in which the Lorentz covariant treatment of nuclear mean-field potential is considered, the fluctuations of net-baryon, net-charge, and deuteron multiplicity distributions in Au+ Au head-on collisions at s N N= 3.0–5.0 GeV are calculated. The results show that the nuclear mean-field potential can significantly enhance the magnitude of baryon number fluctuations in narrow rapidity windows, and this enhancement rapidly weakens with increasing beam energy. However, for proton and net-charge number fluctuations, the mean-field effects are less noticeable than that for baryon number. In addition, for net-charge number fluctuations, the negative binomial distribution agrees well with the calculated results at the midpseudorapidity window. Finally, the event-by-event fluctuations of deuteron number in the coalescence production picture are calculated as well …

New sets of CMS underlying-event parameters (“tunes”) are presented for the pythia8 event generator. These tunes use the NNPDF3. 1 parton distribution functions (PDFs) at leading (LO), next-to-leading (NLO), or nextto-next-to-leading (NNLO) orders in perturbative quantum chromodynamics, and the strong coupling evolution at LO or NLO. Measurements of charged-particle multiplicity and transverse momentum densities at various hadron collision energies are fit simultaneously to determine the parameters of the tunes. Comparisons of the predictions of the new tunes are provided for observables sensitive to the event shapes at LEP, global underlying event, soft multiparton interactions, and double-parton scattering contributions. In addition, comparisons are made for observables measured in various specific processes, such as multijet, Drell–Yan, and top quarkantiquark pair production including jet …

According to the CPT theorem, which states that the combined operation of charge conjugation, parity transformation and time reversal must be conserved, particles and their antiparticles should have the same mass and lifetime but opposite charge and magnetic moment. Here, we test CPT symmetry in a nucleus containing a strange quark, more specifically in the hypertriton. This hypernucleus is the lightest one yet discovered and consists of a proton, a neutron and a Λ hyperon. With data recorded by the STAR detector, – at the Relativistic Heavy Ion Collider, we measure the Λ hyperon binding energy BΛ for the hypertriton, and find that it differs from the widely used value and from predictions, , –, where the hypertriton is treated as a weakly bound system. Our results place stringent constraints on the hyperon–nucleon interaction, and have implications for understanding neutron star interiors, where strange matter …

The charge asymmetry (A ch) dependence of the π− and π+ elliptic flow difference, Δ v 2 (A ch), has been regarded as a sensitive observable for the possible chiral magnetic wave (CMW) in relativistic heavy ion collisions. In this work, we first demonstrate that, due to nonflow backgrounds, the flow measurements by the Q-cumulant method using all charged particles as reference introduce a trivial linear term to Δ v 2 (A ch). The trivial contribution to the slope of triangle flow difference Δ v 3 (A ch) can be negative if the nonflow is dominated by back-to-back pairs. After eliminating the trivial term, we find that the nonflow between like-sign pairs gives rise to an additional positive slope to Δ v 2 (A ch) because of the larger multiplicity dilution to π+(π−) at positive (negative) A ch. We further find that the competition between different π sources can introduce another nontrivial linear-A ch term due to their different multiplicity …

We present a measurement of the first-order azimuthal anisotropy v 1 of deuterons from Au+ Au collisions at s N N= 7.7, 11.5, 14.5, 19.6, 27, and 39 GeV recorded with the STAR experiment at the Relativistic Heavy Ion Collider (RHIC). The energy dependence of the v 1 (y) slope, d v 1/d y| y= 0, for deuterons, where y is the rapidity, is extracted for semicentral collisions (10%–40% centrality) and compared with that of protons. While the v 1 (y) slopes of protons are generally negative for s N N> 10 GeV, those for deuterons are consistent with zero, a strong enhancement of the v 1 (y) slope of deuterons is seen at the lowest collision energy (the largest baryon density) at s N N= 7.7 GeV. In addition, we report the transverse momentum dependence of v 1 for protons and deuterons. The experimental results are compared with transport and coalescence models.

Open heavy-flavor hadrons provide unique probes of the medium produced in ultrarelativistic heavy-ion collisions. Due to their increased mass relative to light-flavor hadrons, long lifetime, and early production in hard-scattering interactions, they provide access to the full evolution of the partonic medium formed in heavy-ion collisions. This paper reports two-dimensional (2D) angular correlations between neutral D mesons and unidentified charged particles produced in minimum-bias Au+ Au collisions at s NN= 200 GeV. D 0 and D 0 mesons are reconstructed via their weak decay to K∓ π±using the Heavy Flavor Tracker in the Solenoidal Tracker at RHIC experiment. Correlations on relative pseudorapidity and azimuth (Δ η, Δ ϕ) are presented for peripheral, midcentral, and central collisions with D 0 transverse momentum from 2–10 GeV/c. Attention is focused on the 2D peaked correlation structure near the …

The transverse momentum (p T) spectra of inclusively produced Λ c+ baryons are measured via the exclusive decay channel Λ c+→ p K− π+ using the CMS detector at the LHC. Spectra are measured as a function of transverse momentum in proton-proton (p p) and lead-lead (PbPb) collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV. The measurement is performed within the Λ c+ rapidity interval| y|< 1 in the p T range of 5–20 GeV/c in p p and 10–20 GeV/c in PbPb collisions. The observed yields of Λ c+ for p T of 10–20 GeV/c suggest a suppression in central PbPb collisions compared to p p collisions scaled by the number of nucleon-nucleon (NN) interactions. The Λ c+/D 0 production ratio in p p collisions is compared to theoretical models. In PbPb collisions, this ratio is consistent with the result from p p collisions in their common p T range.

We use a simple coalescence model to generate f 0 (980) particles for three configurations: a s s meson, a u u s s tetraquark, and a K+ K− molecule. The phase-space information of the coalescing constituents is taken from a multiphase transport (AMPT) simulation of heavy-ion collisions. It is shown that the number of constituent quarks scaling of the elliptic flow anisotropy can be used to discern s s from u u s s and K+ K− configurations.

The second-and third-order azimuthal anisotropy Fourier harmonics of charged particles produced in pPb collisions, at s N N= 8.16 TeV, are studied over a wide range of event multiplicities. Multiparticle correlations are used to isolate global properties stemming from the collision overlap geometry. The second-order “elliptic” harmonic moment is obtained with high precision through four-, six-, and eight-particle correlations and, for the first time, the third-order “triangular” harmonic moment is studied using four-particle correlations. A sample of peripheral PbPb collisions at s N N= 5.02 TeV that covers a similar range of event multiplicities as the pPb results is also analyzed. Model calculations of initial-state fluctuations in pPb and PbPb collisions can be directly compared to the high-precision experimental results. This work provides new insight into the fluctuation-driven origin of the v 3 coefficients in pPb and PbPb …
