The production of three top quarks (3-top) has been identified as a promising signal for probing new physics beyond the Standard Model (BSM). Various BSM models propose a hypothetical Z’ boson that preferentially couples to top quarks, which could manifest as an enhanced 3-top signal, a scenario yet unexplored by the CMS experiment. Recent analyses by ATLAS and CMS indicate that the observed four and three top cross section fits are consistent with predictions of a three top production cross section exceeding that of the Standard Model (SM). This study explores two channels in the fully hadronic final state: tZ’ and tWZ’. Studies of three boosted top quark jets for Z’ masses in the TeV range and the search sensitivity of Run 2 and Run 3 will be reported.
