| 英文摘要 | The decays (B) over bar (0) --> DsJ+K- and (B) over bar (0) --> D(sJ)(-)pi(+) are studied for the first time. A significant signal is observed in the (B) over bar0 --> D-sJ(*) (2317)(+) K- decay channel with B((B) over bar (0) --> D-sJ(*)(2317)K-+(-)) x B(D-sJ(*)(2317)(+) --> D(s)(+)pi(0)) = (5.3(-1.3)(+1.5) +/- 0.7 +/- 1.4) x 10(-5). No signals are observed in the (B) over bar (0) --> D-sJ(*) (2317)(-) pi(+), (B) over bar (0) --> D-sJ(2460)(+) K-, and (B) over bar (0) --> D-sJ(2460)(-) pi(+) decay modes, and upper limits are obtained. The analysis is based on a data set of 140 fb(-1) collected by the Belle experiment at the asymmetric e(+)e(-) collider KEKB. |
