Observation of a pseudo scalar excess at the top quark pair production threshold

Abstract:

A search for resonances in top quark pair (tt?) production in final states with two charged leptons and multiple jets is presented. The analysis is based on proton-proton collision data collected by the CMS experiment at the CERN Large Hadron Collider (LHC) at a center-of-mass energy of TeVs=13 TeV, corresponding to an integrated luminosity of 138 fb?1. The study investigates the invariant mass distribution of the tt? system, along with two angular observables that provide direct sensitivity to the spin correlations between the top quark and antiquark. A significant excess of events is observed near the kinematic tt ...
