| 英文摘要 | A search is presented for the pair production of heavy vector-like t quarks, primarily targeting the t quark decays to a w boson and a b-quark. the search is based on 36: 1 fb(-1) of pp collisions at root s = 13tev 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 one b-tagged jet and a large-radius jet identified as originating from the hadronic decay of a high-momentum w boson. no significant deviation from the standard model expectation is observed in the reconstructed t mass distribution. the observed 95% confidence level lower limit on the t mass are 1350 gev assuming 100% branching ratio to wb. in the su(2) singlet scenario, the lower mass limit is 1170 gev. this search is also sensitive to a heavy vector-like b quark decaying to wt and other final states. the results are thus reinterpreted to provide a 95% con fidence level lower limit on the b quark mass at 1250 gev assuming 100% branching ratio to wt; in the su(2) singlet scenario, the limit is 1080 gev. mass limits on both t and b production are also set as a function of the decay branching ratios. the 100% branching ratio limits are found to be applicable to heavy vector-like y and x production that decay to wb and wt, respectively. |
