| 英文摘要 | The first observation of the b-s(0) -> d-s*(-/+) k-+/- decay is reported using 3.0 fb(-1) of proton-proton collision data collected by the lhcb experiment. the d-s*(-/+) mesons are reconstructed through the decay chain d-s*(-/+) -> gamma d-s(-/+) ((kk +/-)-k--/+pi(-/+)). the branching fraction relative to that for b-s(0) -> d-s*(-)pi(+) decays is measured to be b (b-s(0) -> d-s*k--/+(+/-))/b(b-s(0) -> d-s*(-)pi(+)) = 0.068 +/- 0.005(-0.002)(+0.003), where the first uncertainty is statistical and the second is systematic. using a recent measurement of b(b-s(0) -> d-s*(-)pi(+)), the absolute branching fraction of b-s(0) -> ds*k--/+(+/-) is measured as b(b-s(0) -> d*k--/+(+/-)) = (16.3 +/- 1.2(stat)(-0.5)(+0.7)(syst) +/- 4.8(norm)) x 10(-5), where the third uncertainty is due to the uncertainty on the branching fraction of the normalisation channel. |
