Search for resonant t t ¯production in proton-proton collisions at √s=13 TeV

A search for a heavy resonance decaying into a top quark and antiquark (tt) pair is performed using proton-proton collisions at √ s = 13 TeV. The search uses the data set collected with the CMS detector in 2016, which corresponds to an integrated luminosity of 35.9 fb−1 . The analysis considers...
