Search for pair production of heavy vector-like quarks decaying into high-$p_T$ $W$ bosons and top quarks in the lepton-plus-jets final state in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector
CERN-LHC, ATLAS. Limits on pair production of a heavy vector-like B quark together with its antiparticle, where the B quark decays to a W boson and a top quark. The search is based on 36.1 +\- 0.8 fb^{-1} of pp collisions at sqrt{s} = 13 TeV recorded in 2015 and 2016 with the ATLAS detector at the CERN Large Hadron Collider. Data are analysed in the lepton plus jets final state, including at least four small jets out of which at least one is required to be b-tagged jet and a large-radius jet. Mass limits on B production are set as a function of the decay branching ratios.
Basic event selection:
- ==1 electron or muon: pT >= 30 GeV, in fiducial volume, isolated from jets
- Missing transverse momentum >= 60 GeV
- >=4 small-R jets, with at least one b-tagged
- >=1 large-radius jet
- S_T > 1200 GeV
Comment: Leptonically and hadronically decaying VLQ candidates are reconstructed (see paper) .
Additional selection:
Signal region 1 (RECOSR):
- >=3 large-radius jets
- >=1 hadronic W candidate: W-tagged large-R jet not overlapping with a b-tagged jet
- S_T >= 1500 GeV
- Delta R(lepton, p_T leading b-jet) >= 1
Comment: Final discriminant is the mass of the hadronically decaying VLB candidate
Signal region 2 (BDTSR):
- S_T >= 1200 GeV
- RECOSR veto
Comment: Final discriminant is the BDT discriminant
