Observation of Production in Collisions at with the ATLAS Detector

This Letter reports the observation of W W W production and a measurement of its cross section using 139 fb− 1 of proton-proton collision data recorded at a center-of-mass energy of 13 TeV by the ATLAS detector at the Large Hadron Collider. Events with two same-sign leptons (electrons or muons) and at least two jets, as well as events with three charged leptons, are selected. A multivariate technique is then used to discriminate between signal and background events. Events from W W W production are observed with a significance of 8.0 standard deviations, where the expectation is 5.4 standard deviations. The inclusive W W W production cross section is measured to be 820±100 (stat)±80 (syst) fb, approximately 2.6 standard deviations from the predicted cross section of 511±18 fb calculated at next-to-leading-order QCD and leading-order electroweak accuracy.

Erratum to: Search for single top-quark production via flavour-changing neutral currents at 8 TeV with the ATLAS detector

One correction is noted for the paper. The branching fraction was not included in the conversion of the observed cross-section limit, pb to the coupling constants and and the branching fractions and. The inclusion leads to weaker observed exclusion limits on the coupling constants divided by the scale of new physics of and and on the branching fractions and. The predicted exclusion limits on the coupling constants divided by the scale of new physics are and and on the branching fractions and. Updated distributions of the observed upper limits on the coupling constants for combinations of cgt and ugt channels are shown in Figure 10 a and on the branching fractions in Figure 10 b.

Constraints on Higgs boson production with large transverse momentum using decays in the ATLAS detector

This paper reports constraints on Higgs boson production with transverse momentum above 1 TeV. The analyzed data from proton–proton collisions at a center-of-mass energy of 13 TeV were recorded with the ATLAS detector at the Large Hadron Collider from 2015 to 2018 and correspond to an integrated luminosity of 136 fb− 1. Higgs bosons decaying into b b are reconstructed as single large-radius jets recoiling against a hadronic system and are identified by the experimental signature of two b-hadron decays. The experimental techniques are validated in the same kinematic regime using the Z→ b b process. The 95% confidence-level upper limit on the cross section for Higgs boson production with transverse momentum above 450 GeV is 115 fb, and above 1 TeV it is 9.6 fb. The Standard Model cross section predictions for a Higgs boson with a mass of 125 GeV in the same kinematic regions are 18.4 fb and 0 …

Search for Higgs boson decays into a pair of pseudoscalar particles in the final state with the ATLAS detector in collisions at

This paper presents a search for decays of the Higgs boson with a mass of 125 GeV into a pair of new pseudoscalar particles, H→ a a, where one a-boson decays into a b-quark pair and the other into a muon pair. The search uses 139 fb− 1 of proton-proton collision data at a center-of-mass energy of s= 13 TeV recorded between 2015 and 2018 by the ATLAS experiment at the LHC. A narrow dimuon resonance is searched for in the invariant mass spectrum between 16 GeV and 62 GeV. The largest excess of events above the Standard Model backgrounds is observed at a dimuon invariant mass of 52 GeV and corresponds to a local (global) significance of 3.3 σ (1.7 σ). Upper limits at 95% confidence level are placed on the branching ratio of the Higgs boson to the b b μ μ final state, B (H→ a a→ b b μ μ), and are in the range 0.2–4.0× 10− 4, depending on the signal mass hypothesis.

Search for single production of a vectorlike quark decaying into a Higgs boson and top quark with fully hadronic final states using the ATLAS detector

A search is made for a vectorlike T quark decaying into a Higgs boson and a top quark in 13 TeV proton-proton collisions using the ATLAS detector at the Large Hadron Collider with a data sample corresponding to an integrated luminosity of 139 fb− 1. The Higgs-boson and top-quark candidates are identified in the all-hadronic decay mode, where H→ b b and t→ b W→ b q q′ are reconstructed as large-radius jets. The candidate Higgs boson, top quark, and associated B hadrons are identified using tagging algorithms. No significant excess is observed above the background, so limits are set on the production cross section of a singlet T quark at 95% confidence level, depending on the mass m T and coupling κ T of the vectorlike T quark to Standard Model particles. In the considered mass range between 1.0 and 2.3 TeV, the upper limit on the allowed coupling values increases with m T from a minimum value of 0 …

Search for exotic decays of the Higgs boson into b and missing transverse momentum in pp collisions at = 13 TeV with the ATLAS detector

A search for the exotic decay of the Higgs boson (H) into a b resonance plus missing transverse momentum is described. The search is performed with the ATLAS detector at the Large Hadron Collider using 139 fb− 1 of pp collisions at= 13 TeV. The search targets events from ZH production in an NMSSM scenario where H→, with→, where a is a light pseudoscalar Higgs boson and are the two lightest neutralinos. The decay of the a boson into a pair of b-quarks results in a peak in the dijet invariant mass distribution. The final-state signature consists of two leptons, two or more jets, at least one of which is identified as originating from a b-quark, and missing transverse momentum. Observations are consistent with Standard Model expectations and upper limits are set on the product of cross section times branching ratio for a three-dimensional scan of the masses of the, and a boson.

Luminosity determination in collisions at TeV using the ATLAS detector at the LHC

A precise measurement of the integrated luminosity is a key component of the ATLAS physics programme at the CERN Large Hadron Collider (LHC), in particular for cross-section measurements where it is often one of the leading sources of uncertainty. Searches for new physics phenomena beyond those predicted by the Standard Model also often require accurate estimates of the luminosity to determine background levels and sensitivity. This paper describes the measurement of the luminosity of the proton–proton (????????) collision data sample delivered to the ATLAS detector at a centre-of-mass energy of
