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 higgsinos in compressed mass spectra using low-momentum tracks in collisions at TeV with the ATLAS detector
ATLAS Collaboration
This paper presents two searches for the electroweak production of higgsinos with compressed mass spectra using 140 fb of TeV proton-proton collision data coll…

Measurement of the Higgs boson production in association with top quarks in multilepton final states in collisions at TeV with the ATLAS detector
Atlas Collaboration
A measurement of the associated production of a top-quark pair with the Higgs boson () in multilepton final states is presented. The analysis is based on a data sample o…
