Abstract
The production of boosted top quarks in the high centre-of-mass energy collisions at the LHC is a probe to new phenomena at the TeV scale. Numerous extensions to the Standard Model (SM) predict massive particles whose couplings to top quarks are enhanced. Such massive particles, referred as t¯t resonances, will distort the t¯t invariant mass spectrum relative to the SM expectation. This presentation is dedicated to studies performed by the ATLAS and CMS Collaborations. New techniques were developed to reconstruct boosted top quarks as single objects, both as a top-tagged jet with a substructure in the hadronic decay mode and a jet with a lepton inside in the leptonic decay mode. These techniques were applied in dedicated analyses to search for high mass t¯t resonances. Expected limits and the potential for observation are presented for a luminosity of few hundreds of pb−1.
