| 英文摘要 | The charmless three-body decays b-(s)(0) -> k(s)(0)h(+)h '(-) (where h((')) - pi, k) are analysed using a sample of pp collision data recorded by the lhcb experiment, corresponding to an integrated luminosity of 3 fb(-1). the branching fractions are measured relative to that of the b-0 -> k-s(0) pi(+)pi(-) decay, and are determined to be: b(b-0 -> (ksk +/-)-k-0 pi(-/+))/b(b-0 -> k-s(0)pi(+)pi(-) = 0.123 +/- 0.009 (stat) +/- 0.015 (syst), b(b-0 -> (ksk+k-)-k-0)/b(b-0 -> k-s(0)pi(+)pi(-) = 0.549 +/- 0.018 (stat) +/- 0.033 (syst), b(b-s(0) -> k-s(0) pi(+)pi(-))/b(b-0 -> k-s(0)pi(+)pi(-)) = 0.191 +/- 0.027 (stat) +/- 0.031 (syst) +/- 0.011 (f(s)/f(d)), b(b-0 -> (ksk +/-)-k-0 pi(-/+))/b(b-0 -> k-s(0)pi(+)pi(-) = 1.70 +/- 0.07 (stat) +/- 0.11 (syst) +/- 0.10 (f(s)/f(d)), b(b-0 -> (ksk+k-)-k-0)/b(b-0 -> k-s(0)pi(+)pi(-) is an element of [0.008 - 0.051] at 90% confidence level, where f(s)/f(d) represents the ratio of hadronisation fractions of the b-s(0) and b-0 mesons. |
