Description
Many extensions of the Standard Model predict the presence of particles decaying into a pair of top-quarks, ranging from narrow resonances such as leptophobic topcolor Z’ boson to broader resonances like Kaluza-Klein excitation of the gluon in a Randall-Sundrum model of extra dimensions. The search exploits the technique based on large-radius jets and jet substructure to enhance sensitivity for boosted top quarks produced from high-mass resonance decays. Recent ATLAS results for ttbar resonance searches at LHC Run 1 are presented in this talk. First LHC Run-2 results will be included if available.
