| Summary: | Title screen A search is performed for W′ bosons <https://www.sciencedirect.com/topics/physics-and-astronomy/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 13 TeV. The analyzed data were collected by the CMS experiment between 2016 and 2018 and correspond to an integrated luminosity <https://www.sciencedirect.com/topics/physics-and-astronomy/luminosity> of 137 fb−1. Deep neural network <https://www.sciencedirect.com/topics/physics-and-astronomy/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 3.4 TeV 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. |
