Calibration of the light-flavour jet mistagging efficiency of the b-tagging algorithms with Z+jets events using 139 $$\textrm{fb}^{-1}$$ of ATLAS proton–proton collision data at $$\sqrt{s} = 13$$ TeV
(Springer Nature, 2023-08)
The identification of b-jets, referred to as b-tagging, is an important part of many physics analyses in the ATLAS experiment at the Large Hadron Collider and an accurate calibration of its performance is essential for ...
Evidence for the charge asymmetry in pp → tt¯ production at s = 13 TeV with the ATLAS detector
(Springer Nature, 2023-08)
Inclusive and differential measurements of the top–antitop (tt¯
) charge asymmetry Att¯C
and the leptonic asymmetry Aℓℓ¯C
are presented in proton–proton collisions at s√
= 13 TeV recorded by the ATLAS experiment at ...
Strong Constraints on Jet Quenching in Centrality-Dependent p+Pb Collisions at 5.02 TeV from ATLAS
(American Physical Society (APS), 2023-08-18)
Jet quenching is the process of color-charged partons losing energy via interactions with quark-gluon plasma droplets created in heavy-ion collisions. The collective expansion of such droplets is well described by viscous ...
Measurement of the inclusive tt¯ production cross section in the lepton+jets channel in pp collisions at s=7 TeV with the ATLAS detector using support vector machines
(American Physical Society (APS), 2023-08-01)
A measurement of the top quark pair-production cross section in the
lepton...
Observation of electroweak production of two jets and a Z-boson pair
(Nature Research, 2023-02)
Electroweak symmetry breaking explains the origin of the masses of elementary particles through their interactions with the Higgs field. Besides the measurements of the Higgs boson properties, the study of the scattering ...
Measurement of the production of a W boson in association with a charmed hadron in p p collisions at s = 13 TeV with the ATLAS detector
(American Physical Society (APS), 2023-08)
The production of a
W
boson in association with a single charm quark is studied using...
Search for dark photons from Higgs boson decays via ZH production with a photon plus missing transverse momentum signature from pp collisions at √s = 13 TeV with the ATLAS detector
(Springer, 2023-07-17)
This paper describes a search for dark photons (γd) in proton-proton collisions at s = 13 TeV at the Large Hadron Collider (LHC). The dark photons are searched for in the decay of Higgs bosons (H → γγd) produced through ...
Studies of the muon momentum calibration and performance of the ATLAS detector with pp collisions at s=13 TeV
