| 英文摘要 | We report on a search for (b) over bar (0) --> d-(*()0)(k) over bar (()*()0) decays based on 85 x 10(6) b (b) over bar events collected with the belle detector at kekb. the (b) over bar (0)-->d-0(k) over bar (0) and (b) over bar (0) --> d-0(k) over bar*(0) decays have been observed for the first time with the branching fractions b((b) over bar (0)-->d-0(k) over bar (0))=(5.0(-1.2)(+1.3) +/- 0.6) x 10(-5) and b((b) over bar (0) --> d-0(k) over bar*(0)) = (4.8(-1.0)(+1.1) +/- 0.5) x 10(-5). no significant signal has been found for the (b) over bar (0) --> d*(0)(k) over bar (()*()0) and (b) over bar (0)-->(d) over bar (()*()0)(k) over bar*(0) decay modes, and upper limits at 90% c.l. are presented. |
