A measurement of CP-violating observables in B±→ D* K±and B±→ D* π±decays is made where the photon or neutral pion from the D*→ Dγ or D*→ Dπ 0 decay is not reconstructed. The D meson is reconstructed in the self-conjugate decay modes, D→ π+ π− or D→ K+ K−. The distribution of signal yields in the D decay phase space is analysed in a model-independent way. The measurement uses a data sample collected in proton-proton collisions at centre-of-mass energies of 7, 8, and 13 TeV, corresponding to a total integrated luminosity of approximately 9 fb− 1. The B±→ D* K±and B±→ D* π±CP-violating observables are interpreted in terms of hadronic parameters and the CKM angle γ, resulting in a measurement of γ=(). The total uncertainty includes the statistical and systematic uncertainties, and the uncertainty due to external strong-phase inputs.

The production of mesons in proton-lead collisions at a centre-of-mass energy per nucleon pair of TeV is studied with the LHCb detector using data corresponding to an integrated luminosity of 34 nb. The prompt and nonprompt production cross-sections and the ratio of the to cross-section are measured as a function of the meson transverse momentum and rapidity in the nucleon-nucleon centre-of-mass frame, together with forward-to-backward ratios and nuclear modification factors. The production of prompt is observed to be more suppressed compared to collisions than the prompt production, while the nonprompt productions have similar suppression factors.

Momentum measurements for very high momentum charged particles, such as muons from electroweak vector boson decays, are particularly susceptible to charge-dependent curvature biases that arise from misalignments of tracking detectors. Low momentum charged particles used in alignment procedures have limited sensitivity to coherent displacements of such detectors, and therefore are unable to fully constrain these misalignments to the precision necessary for studies of electroweak physics. Additional approaches are therefore required to understand and correct for these effects. In this paper the curvature biases present at the LHCb detector are studied using the pseudomass method in proton-proton collision data recorded at centre of mass energy

A method is presented to reconstruct charged particles with lifetimes between 10 ps and 10 ns, which considers a combination of their decay products and the partial tracks created by the initial charged particle. Using the baryon as a benchmark, the method is demonstrated with simulated events and proton-proton collision data at TeV, corresponding to an integrated luminosity of 2.0 fb collected with the LHCb detector in 2018. Significant improvements in the angular resolution and the signal purity are obtained. The method is implemented as part of the LHCb Run 3 event trigger in a set of requirements to select detached hyperons. This is the first demonstration of the applicability of this approach at the LHC, and the first to show its scaling with instantaneous luminosity.

The production rate of baryons relative to mesons in collisions at a center-of-mass energy TeV is measured by the LHCb experiment. The ratio of to production cross-sections shows a significant dependence on both the transverse momentum and the measured charged-particle multiplicity. At low multiplicity, the ratio measured at LHCb is consistent with the value measured in collisions, and increases by a factor of with increasing multiplicity. At relatively low transverse momentum, the ratio of to cross-sections is higher than what is measured in collisions, but converges with the ratio as the momentum increases. These results imply that the evolution of heavy quarks into final-state hadrons is influenced by the density of the hadronic environment produced in the collision. Comparisons with a statistical hadronization model and implications for the mechanisms enforcing quark confinement are discussed.

The ratio of branching fractions between and decays is measured with proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 9 fb. The measured value is , where the first uncertainty is statistical and the second is systematic. The branching fraction for decays is determined using the branching fraction of the normalisation channel, resulting in $\mathcal{B}_{B^{0} \rightarrow J/\psi \pi^{0}} = (1.670 \pm 0.077 \pm 0.069 \pm 0.095) \times 10^{-5}$, where the last uncertainty corresponds to that of the external input. This result is consistent with the current world average value and competitive with the most precise single measurement to date.

A measurement of time-dependent CP violation in the decays of B 0 and B 0 mesons to the final states J/ψ (→ μ+ μ−) K S 0, ψ (2S)(→ μ+ μ−) K S 0 and J/ψ (→ e+ e−) K S 0 with K S 0→ π+ π− is presented. The data correspond to an integrated luminosity of 6 fb− 1 collected at a center-of-mass energy of√ s= 13 TeV with the LHCb detector. The CP-violation parameters are measured to be S ψK S 0= 0.717±0.013 (stat)±0.008 (syst) and C ψK S 0= 0.008±0.012 (stat)±0.003 (syst). This measurement of S ψK S 0 represents the most precise single measurement of the CKM angle β to date and is more precise than the current world average. In addition, measurements of the CP-violation parameters of the individual channels are reported and a combination with the LHCb Run 1 measurements is performed.

The production of η and η′ mesons is studied in proton-proton and proton-lead collisions collected with the LHCb detector. Proton-proton collisions are studied at center-of-mass energies of 5.02 and 13 TeV and proton-lead collisions are studied at a center-of-mass energy per nucleon of 8.16 TeV. The studies are performed in center-of-mass (cm) rapidity regions 2.5< y c. m.< 3.5 (forward rapidity) and− 4.0< y c. m.<− 3.0 (backward rapidity) defined relative to the proton beam direction. The η and η′ production cross sections are measured differentially as a function of transverse momentum for 1.5< p T< 10 GeV and 3< p T< 10 GeV, respectively. The differential cross sections are used to calculate nuclear modification factors. The nuclear modification factors for η and η′ mesons agree at both forward and backward rapidity, showing no significant evidence of mass dependence. The differential cross sections of η …

The production of ψ (2S) mesons in proton-lead collisions at a centre-of-mass energy per nucleon pair of= 8. 16 TeV is studied with the LHCb detector using data corresponding to an integrated luminosity of 34 nb− 1. The prompt and nonprompt ψ (2S) production cross-sections and the ratio of the ψ (2S) to J/ψ cross-section are measured as a function of the meson transverse momentum and rapidity in the nucleon-nucleon centre-of-mass frame, together with forward-to-backward ratios and nuclear modification factors. The production of prompt ψ (2S) is observed to be more suppressed compared to pp collisions than the prompt J/ψ production, while the nonprompt productions have similar suppression factors.

Using a sample of approximately 349 000 B s 0 signal decays with an invariant K+ K− mass in the vicinity of the ϕ (1020) resonance, the C P-violating phase ϕ s is measured, along with the difference in decay widths of the light and heavy mass eigenstates of the B s 0− Bs 0 system, Δ Γ s, and the difference of the average B s 0 and B 0 meson decay widths, Γ s− Γ d.

The first measurement of the Z boson production cross-section at centre-of-mass energy= 5. 02 TeV in the forward region is reported, using pp collision data collected by the LHCb experiment in year 2017, corresponding to an integrated luminosity of 100±2 pb− 1. The production cross-section is measured for final-state muons in the pseudorapidity range 2. 0< η< 4. 5 with transverse momentum p T> 20 GeV/c. The integrated cross-section is determined to be

A measurement of time-dependent C P violation in the decays of B 0 and B 0 mesons to the final states J/ψ (→ μ+ μ−) K S 0, ψ (2 S)(→ μ+ μ−) K S 0 and J/ψ (→ e+ e−) K S 0 with K S 0→ π+ π− is presented. The data correspond to an integrated luminosity of 6 fb− 1 collected at a center-of-mass energy of s= 13 TeV with the LHCb detector. The C P-violation parameters are measured to be S ψ K S 0= 0.717±0.013 (stat)±0.008 (syst) and C ψ K S 0= 0.008±0.012 (stat)±0.003 (syst). This measurement of S ψ K S 0 represents the most precise single measurement of the CKM angle β to date and is more precise than the current world average. In addition, measurements of the C P-violation parameters of the individual channels are reported and a combination with the LHCb Run 1 measurements is performed.
