Abstract: We report the first measurement of the ? lepton polarization P?(D?) in the decay B?D??-?? as well as a new measurement of the ratio of the branching fractions R(D?)=B(B?D??-??)/B(B?D?-?), where - denotes an electron or a muon, and the ? is reconstructed in the modes ?-??-?? and ?-??-??. We use the full data sample of 772�106 BB pairs recorded with the Belle detector at the KEKB electron-positron collider. Our results, P?(D?)=-0.38�0.51(stat)-0.16+0.21(syst) and R(D?)=0.270�0.035(stat)-0.025+0.028(syst), are consistent with the theoretical predictions of the standard model. � 2017 American Physical Society.
