摘要: We study the charmful decays of the two-body B-b -> BnMc decays, where B-b represents the antitriplet of (Lambda(b), Xi(0)(b), Xi(-)(b)), B-n stands for the baryon octet, and M-c denotes the charmed meson of D-(s)((*)), eta(c) and J/psi. Explicitly, we predict that B(Lambda(b) -> D(s)(-)p) = (1.8 +/- 0.3) x 10(-5), which is within the measured upper bound of B(Lambda(b) -> D(s)(-)p) < 4.8(5.3) x 10(-4) at 90% (95%) C.L., and reproduce B(Lambda(b) -> J/psi Lambda) = (3.3 +/- 2.0) x 10(-4) and B(Xi(-)(b) -> J/psi Xi(-)) = (5.1 +/- 3.2) x 10(-4) in agreement with the data. Moreover, we find that B(Lambda(b) -> Lambda eta(c)) = (1.5 +/- 0.9) x 10(-4), B(Xi(-)(b) -> Xi(-)eta(c)) = (2.4 +/- 1.5) x 10(-4) and B(Xi(0)(b) -> Xi(0)eta(c), Xi(0)J/psi) = (2.3 +/- 1.4, 4.9 +/- 3.0) x 10(-4), which are accessible to the experiments at the LHCb.
