Abstract
A number of new physics models suggest that a heavy $Z^\prime$ or $W^\prime$ particle may decay through heavy fermions. In some such models, decays with intermediate new particles may have a higher branching ratio than decays to standard model particles. These new models are not currently excluded by experimental searches, resulting in a gap in the coverage of new physics models with heavy bosons.
A search for $Z^\prime\rightarrow tT^\prime$, restricted to decays with a single highly energetic lepton, is outlined. Data from proton-proton collisions at the CMS detector, with a center of mass energy of 13 TeV, and corresponding to an integrated luminosity of 2.6 fb$^{-1}$ are analyzed. A new background estimate relying on recent developments in jet substructure is detailed and expected limits are presented.
