Title: Search for High-Mass Top Quark Pair Resonances with the CMS Experiment

Abstract

I present a search for new massive particles decaying to a pair of top quarks with the CMS detector at the LHC, using 36 fb$$^{-1}$$ of proton-proton collision data recorded in 2016, at a center-of-mass energy of 13 TeV. In the high mass ranges accessible by the LHC at these energies, the top quarks are produced with high transverse momenta: the products of hadronically decaying top quarks are reconstructed as a single jet. Specific reconstruction algorithms and selections are employed to address the identification of boosted top quark signatures. The search is performed by measuring the invariant mass distribution of the top-quark pair and testing for deviations from the expected Standard Model background. The results are presented in terms of expected upper limits on the production cross section of several models, including those of Randall-Sundrum Kaluza-Klein gluon and $$Z\prime$$ boson production. The results are then compared with those of previous searches.
