| 英文摘要 | We report studies of the cabibbo-suppressed decay b+/- --> dcpk+/-, where d-cp denotes cp eigenstates of the d-0 - (d) over bar (0) system. the analysis is based on a 29.1 fb(-1) sample collected at the y(4s) resonance with the belle detector at the kekb asymmetric e(+)e(-) storage ring. we measure ratios of branching fractions, relative to cabibbo-favored b+/--->d(cp)pi+/-, of b>(b- --> d1k-)/b(b- --> d(1)pi(-)) = 0.125 +/-0.036 +/- 0.010 and b(b- --> d2k-)/b(b- --> d(2)pi(-)) = 0.119 +/- 0.028 +/- 0.006; the index 1 (2) denotes the cp = +1 (-1) eigenstate. we also extract the partial rate asymmetries for b+/- --> dcpk+/-, finding a(1) = 0.29 +/- 0.26 +/- 0.05 and a(2) = -0.22 +/- 0.24 +/- 0.04. |
