Description
A search for a heavy resonance decaying into a top quark and a W boson in proton-
proton collisions at √s = 13 TeV is presented. The data was recorded by CMS detector and correspond to an integrated luminosity of up to 138 fb−1. The analysis is performed in the lepton+jets final state, where the top quark is reconstructed from an electron or muon, missing transverse momentum and a jet identified as originat- ing from a bottom quark. The W boson from the resonance decay is reconstructed as a single large-radius jet, identified by its characteristic substructure. The results are interpreted in the context of an excited bottom quark b∗ model. No statistically significant excess over the expected background is found, and b∗ quarks with left- handed, right-handed, and vector-like chiralities are excluded at 95% confidence level for masses below 2.4, 2.8, and 3.1 TeV, respectively.
