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…
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…
Transforming jet flavour tagging at ATLAS
ATLAS Collaboration
Jet flavour tagging enables the identification of jets originating from heavy-flavour quarks in proton-proton collisions at the Large Hadron Collider, playing a critical role in it…
Observation of double parton scattering in same-sign W boson pair production in pp collisions at TeV with the ATLAS detector
ATLAS Collaboration
This letter reports the measurement of double parton scattering in same-sign W boson pair production with the ATLAS detector. The data set used corresponds to an integrated luminos…
