英文摘要	Although the two-body charmed decays B-(s) -> (D) over bar (()((s))()) P and (D) over bar (()((s))()) V, where P (V) denotes a light pseudoscalar (vector) meson, are Cabbibo-Kobayashi-Maskawa (CKM) suppressed compared with the B-(s) -> D-(s)(()()) P and D-(s)(()()) V decays, they are important in the CKM angle gamma = phi(3) extraction method. We investigated these decays in the perturbative QCD approach to the leading order of m(D)/m(B) and Lambda(QCD)/m(D) expansion. We find that the nonfactorizable emission diagrams and the annihilation diagrams are not negligible in many of these channels. The numerical results show that most channels have branching ratios with an order of 10(-6) or 10(-7). The ratio needed for the CKM angle gamma extraction is estimated as r = \|A(B- -> (D) over bar K-0(-))\|/\|A(B- -> (DK-)-K-0)\| = 0.092(-0.003-0.003)(+ 0.012+ 0.003), which is too small for the experiments. Some of the B-(s) -> (D) over bar ((s)) V decays have a very large transversely polarized contribution that can reach 80%.
