A search is performed for W ‘ bosons decaying to a top and a bottom
quark in the all-hadronic final state, in proton-proton collisions at a
center-of-mass energy of 13TeV. The analyzed data were collected by the
CMS experiment between 2016 and 2018 and correspond to an integrated
luminosity of 137fb(-1). Deep neural network algorithms are used to
identify the jet initiated by the bottom quark and the jet containing
the decay products of the top quark when the W ‘ boson from the top
quark decays hadronically. No excess above the estimated standard model
background is observed. Upper limits on the production cross sections of
W ‘ bosons decaying to a top and a bottom quark are set. Both left- and
right-handed W ‘ bosons with masses below 3.4TeV are excluded at 95%
confidence level, and the most stringent limits to date on W ‘ bosons
decaying to a top and a bottom quark in the all-hadronic final state are
obtained. (C) 2021 The Author(s). Published by Elsevier B.V
