Search for third-generation vector-like leptons in pp collisions at √s = 13 TeV with the ATLAS detector ATLAS Collaboration
Abstract
A search for vector-like leptons in multilepton (two, three, or four-or-more
electrons plus muons) final states with zero or more hadronic τ -lepton decays is presented.
The search is performed using a dataset corresponding to an integrated luminosity of
139 fb−1
of proton-proton collisions at a centre-of-mass energy of 13 TeV recorded by the
ATLAS detector at the LHC. To maximize the separation of signal and background, a
machine-learning classifier is used. No excess of events is observed beyond the Standard
Model expectation. Using a doublet vector-like lepton model, vector-like leptons coupling
to third-generation Standard Model leptons are excluded in the mass range from 130 GeV
to 900 GeV at the 95% confidence level, while the highest excluded mass is expected to be
970 GeV.
