The search is based on data from proton-proton collisions at 13 TeV, collected with the CMS detector, corresponding to an integrated luminosity of 138 fb$^{-1}$. Possible CP violation effects are evaluated by measuring uncorrected 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 $\\pm$ 0.10 (stat) $\\pm$ 0.07 (syst), and the asymmetries exhibit no evidence for CP-violating effects, consistent with expectations from the standard model.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.114781.v1/t1","@type":"Dataset","description":"Results for the measurement of the effective asymmetries for each observable for the separate electron and muon channels, as well...","name":"Effective asymmetries A'_{CP} measurement"},{"@id":"https://doi.org/10.17182/hepdata.114781.v1/t2","@type":"Dataset","description":"Results for the measurement of the dimensionless CEDM for each observable and the combined lepton+jets channel.","name":"Dimensionless CEDM d_{tG} measurement"},{"@id":"https://doi.org/10.17182/hepdata.114781.v1/t3","@type":"Dataset","description":"Results for the measurement of the CP-violating asymmetries for each observable for the combined lepton+jets channel.","name":"CP-violating asymmetries A_{CP} measurement"},{"@id":"https://doi.org/10.17182/hepdata.114781.v1/t4","@type":"Dataset","description":"Results for the covariance matrix where the parameters a, b, c, and d are taken from a linear fit to...","name":"Covariance matrix"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2077553?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/114781"}],"inLanguage":"en","name":"Search for CP violation using $\\mathrm{t\\bar{t}}$ events in the lepton+jets channel in pp collisions at $\\sqrt{s}$ = 13 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2077553?version=1","version":1}
