英文摘要	A search is presented for the production of vector-like quark pairs, t (t) over bar or y (y) over bar, with electric charge of 2/3(t) or -4/3(y), in proton-proton collisions at root s= 13 tev. the data were collected by the cms experiment at the lhc in 2016 and correspond to an integrated luminosity of 35.8 fb(-1). the t and y quarks are assumed to decay exclusively to a w boson and a b quark. the search is based on events with a single isolated electron or muon, large missing transverse momentum, and at least four jets with large transverse momenta. in the search, a kinematic reconstruction of the final state observables is performed, which would permit a signal to be detected as a narrow mass peak (approximate to 7% resolution). the observed number of events is consistent with the standard model prediction. assuming strong pair production of the vector-like quarks and a 100% branching fraction to bw, a lower limit of 1295 gev at 95% confidence level is set on the t and y quark masses.
