Abstract: The polarization of T leptons is measured using leptonic and hadronic T lepton decays in Z -> T+T- events in proton-proton collisions at Vs = 13 TeV recorded by CMS at the CERN LHC with an integrated luminosity of 36.3 fb-1. The measured T lepton polarization at the Z boson mass pole is P?T (Z) = ?0.144 ± 0.006 (stat) ± 0.014 (syst) = -0.144 ± 0.015, in good agreement with the measurement of the ? lepton asymmetry parameter of AT = 0.1439 ± 0.0043 = - PT (Z) at LEP
