Evidence for the dimuon decay of the Higgs boson in pp collisions with the ATLAS detector
ATLAS Collaboration
A search for the dimuon decay of the Higgs boson is presented based on pp collision data recorded by ATLAS during Run 3 of the Large Hadron Collider, corresponding to an integrated…
A continuous calibration of the ATLAS flavour-tagging classifiers via optimal transportation maps
ATLAS Collaboration
A calibration of the ATLAS flavour-tagging algorithms using a new calibration procedure based on optimal transportation maps is presented. Simultaneous, continuous corrections to t…
Search for a new pseudoscalar decaying into a pair of bottom and antibottom quarks in top-associated production in =13 TeV proton-proton collisions with the ATLAS detector
ATLAS Collaboration
A search for a pseudoscalar produced in association with a top-quark pair, or in association with a single top quark plus a boson, with the pseudoscalar decaying into -q…
Search for heavy neutral leptons in decays of W bosons using leptonic and semi-leptonic displaced vertices in TeV collisions with the ATLAS detector
ATLAS Collaboration
A search is performed for long-lived heavy neutral leptons (HNLs), produced through the decay of a boson along with a muon or electron. Two channels are explored: a leptonic ch…
Measurement of the top quark mass with the ATLAS detector using events with a high transverse momentum top quark
ATLAS Collaboration
The mass of the top quark is measured using top-antitop-quark pair events with high transverse momentum top quarks. The dataset, collected with the ATLAS detector in proton--proton…
Estimation of backgrounds from jets misidentified as -leptons using the Universal Fake Factor method with the ATLAS detector
ATLAS Collaboration
Processes with -leptons in the final state are important for Standard Model measurements and searches for physics beyond the Standard Model. The ATLAS experiment at the Large Ha…
