| 英文摘要 | We report the first observation of a baryonic b-s(0) decay, b-s(0). p (lambda) over bark(-), using proton-proton collision data recorded by the lhcb experiment at center-of-mass energies of 7 and 8 tev, corresponding to an integrated luminosity of 3.0 fb(-1). the branching fraction is measured to be b(b-s(0) -> p (lambda) over bar k-)+ b(b-s(0) -> p (lambda) over bar k+) [5.46 +/- 0.61 +/- 0.57 +/- 0.50(b) +/- 0.32(f(s)/(d))] x 10(-6), where the first uncertainty is statistical and the second systematic, the third uncertainty accounts for the experimental uncertainty on the branching fraction of the b-0 -> p (lambda) over bar pi(-) decay used for normalization, and the fourth uncertainty relates to the knowledge of the ratio of b-quark hadronization probabilities f(s)/f(d). |
