Description
This paper presents the search for the production of a Higgs boson in
association with a single top quark (tHq), using data collected in
proton-proton collisions at a center-of-mass energy of 8 TeV
corresponding to an integrated luminosity of 19.7 fb-1. The
search exploits a variety of Higgs boson decay modes resulting in final
states with photons, bottom quarks, and multiple charged leptons,
including tau leptons, and employs a variety of multivariate techniques
to maximize sensitivity to the signal. The analysis is optimized for the
opposite sign of the Yukawa coupling to that in the standard model,
corresponding to a large enhancement of the signal cross section. In the
absence of an excess of candidate signal events over the background
predictions, 95% confidence level observed (expected) upper limits on
anomalous tHq production are set, ranging between 600 (450) fb and 1000
(700) fb depending on the assumed diphoton branching fraction of the
Higgs boson. This is the first time that results on anomalous tHq
production have been reported. [Figure not available: see fulltext.]
