Search for CP violation using t (t)over-bar events in the lepton plus jets channel in pp collisions at SQUARE ROOTs=13 TeV
Original language description
Results are presented on a search for CP violation in the production and decay of top quark-antiquark pairs in the lepton+jets channel. The search is based on data from proton-proton collisions at root s = 13TeV, collected with the CMS detector, corresponding to an integrated luminosity of 138 fb(-1). Possible CP violation effects are evaluated by measuring asymmetries in observables constructed from linearly independent four-momentum vectors of the final-state particles. The dimensionless chromoelectric dipole moment of the top quark obtained from the observed asymmetries is measured to be 0.04 +/- 0.10 (stat)+/- 0.07(syst), and the asymmetries exhibit no evidence for CP-violating effects, consistent with expectations from the standard model.
