We report the first measurement of the t lepton polarization PtðDÞ in the decay B¯ ? Dt- ¯?t as well as a new measurement of the ratio of the branching fractions RðDÞ ¼ BðB¯ ? Dt- ¯?tÞ=BðB¯ ? Dl- ¯?lÞ, where l- denotes an electron or a muon, and the t is reconstructed in the modes t- ? p-?t and t- ? ?-?t
