Description
A search for single production of vector-like top quark partners (T)
decaying into a Higgs boson and a top quark is performed using data from
pp collisions at a centre-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.
