Abstract

The possibility of discovering top-antitop resonances with masses of 700, 1000, 1500, 2000, and 3000 GeV/c2 at proton-proton collision energy of 14 TeV in the center of a mass system is considered. The minimum cross sections for the resonance production necessary for their detection in a lepton + jets channel of \( t\mathop t\limits^ - \) pair decay with a 5σ confidence level is estimated. The analysis is performed both with and without taking into account the possibility of hadronic jets reconstruction from b quarks (b-tagging).
