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…

Observation of production at TeV with the ATLAS detector
ATLAS Collaboration
A search for the production of three massive vector bosons, , in proton-proton collisions at TeV is performed using data with an integrated luminosity…

Test of lepton flavour universality in -boson decays into electrons and -leptons using collisions at TeV with the ATLAS detector
ATLAS Collaboration
A measurement of the ratio of the branching fractions, , is performed using a sample of bosons originating from top-quark decays to final s…
