Measurements of W+W- production in decay topologies inspired by searches for electroweak supersymmetry
(Springer Nature, 2023-08)
This paper presents a measurement of fiducial and differential cross-sections for W+W−
production in proton–proton collisions at s√=13
TeV with the ATLAS experiment at the Large Hadron Collider using a dataset corresponding ...
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 ...
Search for flavor-changing neutral-current couplings between the top quark and the Z boson with proton-proton collisions at s=13 TeV with the ATLAS detector
(American Physical Society (APS), 2023-08-01)
Search for the charged-lepton-flavor-violating decay Z→eμ in pp collisions at s=13 TeV with the ATLAS detector
(American Physical Society (APS), 2023-08-01)
Combination of inclusive top-quark pair production cross-section measurements using ATLAS and CMS data at s = 7 and 8 TeV
(Springer Nature, 2023-07-27)
A combination of measurements of the inclusive top-quark pair production cross-section performed by ATLAS and CMS in proton–proton collisions at centre-of-mass energies of 7 and 8 TeV at the LHC is presented. The cross-sections ...
A search for heavy Higgs bosons decaying into vector bosons in same-sign two-lepton final states in pp collisions at s = 13 TeV with the ATLAS detector
(Springer Nature, 2023)
A search for heavy Higgs bosons produced in association with a vector boson and decaying into a pair of vector bosons is performed in final states with two leptons (electrons or muons) of the same electric charge, missing ...
