Search for a heavy resonance decaying to a top quark and a W boson at $\sqrt{s} = 13~\mathrm{TeV}$ in the fully hadronic final state

A search for a heavy resonance decaying to a top quark and a W boson in the fully hadronic final state is presented. The analysis is performed using proton-proton collisions at a center-of-mass energy of $13~\mathrm{TeV}$. The search uses data corresponding to an integrated luminosity of $137~\mathrm{fb}^{-1}$ recorded by the CMS experiment at the LHC. The analysis is focused on heavy resonances, where the decay products of each top quark or W boson are expected to be reconstructed as a single, large radius jet with a distinct substructure. An excited bottom quark, $\mathrm{b}^\ast$, is used as a benchmark model when setting limits on the cross section for a heavy resonance decaying to a top quark and a W boson. The hypotheses of $\mathrm{b}^\ast$ quarks with left-handed, right-handed, and vector-like chirality are excluded at $95\%$ confidence level for masses below 2.6, 2.8, and 3.1 TeV, respectively.
