Measurement of CP violating asymmetries in top quark pair production with data collected by the CMS experiment and corresponding to an integrated luminosity of 36 fb-1 in pp collisions at √s=13TeV. The asymmetries are measured with T-odd triple production correlations, constructed by linearly independent four-momentum vectors associated with the final states particle of top quark decays. The resulting CP violating parameter ACP is evaluated by counting asymmetry of the T-odd observables.
