Measurement of the top-quark mass using decays with a meson at 13 TeV with the ATLAS detector
ATLAS Collaboration
The top-quark mass is measured using top-quark decays producing an isolated lepton and meson reconstructed in its decay mode. The data sample was recorded with the A…
Measurement of coherent exclusive production in ultraperipheral Pb+Pb collisions at TeV with the ATLAS detector
ATLAS Collaboration
The ATLAS experiment has performed a measurement of coherent exclusive production in ultraperipheral Pb+Pb collisions at TeV. The data…
Search for Beyond the Standard Model physics with anomaly detection in multilepton final states in collisions at TeV with the ATLAS detector
ATLAS Collaboration
A model-agnostic search for Beyond the Standard Model physics is presented, targeting final states with at least four light leptons (electrons or muons). The search regions are sep…
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…
Observation of production at 13 TeV with the ATLAS detector
ATLAS Collaboration
This paper presents the first observation of top-quark pair production in association with two photons (). The measurement is performed in the single-lepton decay chann…
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…
