英文摘要	A search for single production of vector-like top quark partners (t) decaying into a higgs boson and atop quark is performed using data from pp collisions at acentre-of-mass energy of 13 tev collected by the cms experiment at the cern lhc, corresponding to an integrated luminosity of 2.3 fb(-1). the top quark decay includes an electron or a muon while the higgs boson decays into a pair of b quarks. no significant excess over standard model backgrounds is observed. exclusion limits on the product of the production cross section and the branching fraction are derived in the t quark mass range 700 to 1800 gev. for a mass of 1000 gev, values of the product of the production cross section and the branching fraction greater than 0.8 and 0.7 pb are excluded at 95% confidence level, assuming left-and right-handed coupling of the t quark to standard model particles, respectively. this is the first analysis setting exclusion limits on the cross section of singly produced vector-like t quarks at a centre-of-mass energy of 13 tev.
