英文摘要	In anticipation of abundant B* data samples at high-luminosity heavy-flavor experiments in the future, the tree-dominated semileptonic (B) over bar (u,d,s)* -> Pl(-)(v) over bar (l) (P = D, D-s, pi, K) decays are studied within the Standard Model. After a detailed calculation of the helicity amplitudes, the theoretical predictions for branching fraction (decay rate), lepton spin asymmetry, forward-backward asymmetry and ratio R-D((L)) are firstly presented. It is found that the CKM-favored (B) over bar -> Dl(-)(v) over bar (l) decays have relatively large branching fractions of O(10(-9))similar to O(10(-7)), and are in the scope of running LHC and forthcoming SuperKEKB/Belle-II experiments.
