330 | _aA search is presented for a heavy spin-1 resonance Z′Z′ decaying to a top quark and a vector-like top quark partner TT in the lepton + jets final state. The search is performed using a data set of pp pp collisions at a centre-of-mass energy of 13TeVTeV corresponding to an integrated luminosity of 35.9fb−135.9fb−1 as recorded by the CMS experiment at the CERN LHC in the year 2016. The analysis is optimised for final states arising from the TT decay modes to a top quark and a Higgs or ZZ boson (T→Ht,ZtT→Ht,Zt). The event selection makes use of resolved and merged top quark decay products, as well as decays of boosted Higgs bosons and ZZ and WW bosons using jet substructure techniques. No significant deviation from the standard model background expectation is observed. Exclusion limits on the product of the cross section and branching fraction for Z′→tT,T→Ht,Zt,WbZ′→tT,T→Ht,Zt,Wb are presented for various combinations of the Z′Z′ resonance mass and the vector-like TT quark mass. These results represent the most stringent limits to date for the decay mode Z′→tT→tHtZ′→tT→tHt. In a benchmark model with extra dimensions, invoking a heavy spin-1 resonance G∗G∗, masses of the G∗G∗ between 1.5 and 2.3TeVTeV and between 2.0 and 2.4TeVTeV are excluded for TT masses of 1.2 and 1.5TeVTeV, respectively. | ||
