Search for a W' boson decaying to a top and a bottom quark at $\sqrt{s}= $ 13 TeV
Abstract: A search is performed for a W' boson decaying to a top and a bottom quark in proton-proton collisions at a center-of-mass energy of 13 TeV. The analyzed data have been collected by the CMS Collaboration between 2016 and 2018 and correspond to an integrated luminosity of 137 fb$^{-1}$. Deep neural network algorithms are used to identify the jets initiated by the b quark and also the jets 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 and upper limits on the production cross section of W' bosons are set. Both left- and right-handed W' bosons with masses below 3.4 TeV are excluded at 95% confidence level. These results are the best limits to date on W' bosons decaying to a top and a bottom quark in the all-handronic final state.
