Abstract:
We present a search for the production of heavy resonances decaying into top-antitop quark pairs. The analysis is performed in the lepton+jets channel using of data collected in proton-proton collisions at with the CMS detector. The selection is optimized for heavy resonance masses, where the top quarks have large Lorentz-boosts. This results in non-isolated leptons from the decay and two or more quarks reconstructed in a single jet from the decay. These jets are identified using top-tagging algorithms. No evidence for resonant production is found and upper limits on the production cross section of heavy resonances are set.Note:
