Abstract
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 data from
proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an integrated
luminosity of 137 fb−1
recorded by the CMS experiment at the LHC. The search 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. The production
of an excited bottom quark, b
∗
, is used as a benchmark when setting limits on the cross
section for a heavy resonance decaying to a top quark and a W boson. The hypotheses of
b
∗
quarks with left-handed, right-handed, and vector-like chiralities are excluded at 95%
confidence level for masses below 2.6, 2.8, and 3.1 TeV, respectively. These are the most
stringent limits on the b
∗
quark mass to date, extending the previous best limits by almost
a factor of two.
