Search for pair-production of vector-like quarks in lepton+jets final states containing at least one ????-tagged jet using the Run 2 data from the ATLAS experiment

Popis výsledku v původním jazyce

A search is presented for the pair-production of heavy vector-like quarks in the lepton+jets final state using 140 fb-1 of proton-proton collisions at SQUARE ROOT???? = 13 TeV collected with the ATLAS detector. The search is optimised for vector-like top-quarks (???? ) that decay into a ???? boson and a ????-quark, with one ???? boson decaying leptonically and the other hadronically. Other vector-like quark flavours and decay modes are also considered. Events are selected with one high transverse-momentum electron or muon, large missing transverse momentum, a largeradius jet identified as a ???? boson, and multiple small-radius jets, at least one of which is ????-tagged. Vector-like ???? -quarks with 100% branching ratio to ???????? are excluded at 95% CL for masses below 1700 GeV. These limits are also applied to vector-like ???? -quarks, which decay exclusively into a ???? boson and a ????-quark. Isospin singlets with B(???? RIGHTWARDS ARROW???????? RATIO ???????? RATIO ????????) = 1DIVISION SLASH2 RATIO 1DIVISION SLASH4 RATIO 1DIVISION SLASH4 are excluded for masses below 1360 GeV.
