Search for a heavy resonance decaying to tH in the boosted all-hadronic final state

A search for a heavy resonance decaying to a top quark and a Higgs boson in the fully hadronic final state is presented. The analysis is performed using the full Run2 dataset recorded by the CMS experiment at the LHC. The search is focused on heavy resonances, where the decay products of each top quark or Higgs boson are expected to be reconstructed as a single, large-radius jet with a distinct substructure. The production of a vector-like top quark, T', is used as a benchmark when setting limits on the cross section for a heavy resonance decaying to a top quark and a Higgs boson.
