Search for a light charged Higgs boson in t → H±b decays, with H± → cb, in the lepton+jets final state in proton-proton collisions at s = 13 TeV with the ATLAS detector
(Springer Nature, 2023)
A search for a charged Higgs boson, H±, produced in top-quark decays, t → H±b, is presented. The search targets H± decays into a bottom and a charm quark, H± → cb. The analysis focuses on a selection enriched in top-quark ...
Searches for exclusive Higgs and Z boson decays into a vector quarkonium state and a photon using 139 fb-1 of ATLAS s=13 TeV proton–proton collision data
(Springer Nature, 2023)
Searches for the exclusive decays of Higgs and Z bosons into a vector quarkonium state and a photon are performed in the...
Measurements of differential cross sections of Higgs boson production through gluon fusion in the H→WW∗→eνμν final state at s=13 TeV with the ATLAS detector
(Springer Nature, 2023)
Higgs boson production via gluon–gluon fusion is measured in the WW∗→eνμν
decay channel. The dataset utilized corresponds to an integrated luminosity of 139 fb−1
collected by the ATLAS detector from s√=13
TeV ...

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 ...
