Measurement of the W-boson mass and width with the ATLAS detector using proton-proton collisions at = 7 TeV
ATLAS Collaboration
Proton-proton data recorded by the ATLAS detector in 2011, at a centre-of-mass energy of 7 TeV, have been used for an improved determination of the W-boson mass and a first measure…

Search for short- and long-lived axion-like particles in decays with the ATLAS experiment at the LHC
ATLAS Collaboration
Presented is the search for anomalous Higgs boson decays into two axion-like particles (ALPs) using the full Run 2 data set of 140 fb of proton-proton collisions at a centre…

Search for heavy right-handed Majorana neutrinos in the decay of top quarks produced in protonproton collisions at = 13 TeV with the ATLAS detector
ATLAS Collaboration
A search for heavy right-handed Majorana neutrinos is performed with the ATLAS detector at the CERN Large Hadron Collider, using the 140 of proton-proton collisi…
