About the Possibility of the Top-Antitop Resonance Searches at the LHC
The possibility of discovering top-antitop resonances with masses 700, 1000, 1500, 2000 and 3000 GeV/c<sup>2</sup> at the proton-proton colliding energy 14 TeV is discussed. The minimal cross sections of the resonance production in the lepton+jets decay channel with different masses necessary to achieve the 5<i>σ</i> confidence level both with taking into consideration a possibility of jets reconstruction from 6-quarks and without it are estimated.
