abstract = {The presented work is a search for single production of
vector-like T quarks.Vector-like quarks are common among
non-SUSY theories that strive to solve the hierarchy
problem.The search is undertaken with 2.3$\,$fb of
proton-proton collisions at a centre of mass energy of
$\sqrt s=13\,$TeV, recorded with the CMS experiment at the
CERN LHC in 2015.The T quark decay channel into a top quark
and a Higgs boson is considered.A mass-range from 700$\,$GeV
up to 1800$\,$GeV is scanned, where the top quark and Higgs
boson acquire a significant Lorentz boost.An electron or
muon in the final state is required, as well as a collimated
pair of b quarks from the decay of the boosted Higgs
boson.The search is performed as a shape analysis with a
signal plus background model, fitted to the data.The shape
of the background is extracted from a signal-depleted
control region in the data.The background shape describes
the observed data well and no excess of events is
seen.Exclusion limits are derived for the single T quark
production cross section times the branching fraction of the
T quark decay into a Higgs boson and a top quark.A Bayesian
statistical method is applied.At 95\\% confidence level,
values of 0.49$\,$pb and 0.18$\,$pb (0.42$\,$pb and
0.14$\,$pb) for T quark masses of 1200$\,$GeV and
1700$\,$GeV, respectively, are excluded for T quark
production in association with b (top) quarks.These are the
first results on singly produced vector-like quarks
published by the CMS Collaboration and the first results
from the LHC at $\sqrt s=13\,$TeV.},
