| 英文摘要 | The results of a search for vector-like top quarks using events with exactly one lepton, at least four jets, and large missing transverse momentum are reported. the search is optimised for pair production of vector-like top quarks in the z(->nu nu) t + x decay channel. lhc pp collision data at a centre-of-mass energy of root s = 13tev recorded by the atlas detector in 2015 and 2016 are used, corresponding to an integrated luminosity of 36.1 fb(-1). no significant excess over the standard model expectation is seen and upper limits on the production cross-section of a vector-like t quark pair as a function of the t quark mass are derived. the observed (expected) 95% cl lower limits on the t mass are 870 gev (890 gev) for the weak-isospin singlet model, 1.05 tev (1.06 tev) for the weak-isospin doublet model and 1.16 tev (1.17 tev) for the pure zt decay mode. limits are also set on the mass as a function of the decay branching ratios, excluding large parts of the parameter space for masses below 1 tev. |
