| 英文摘要 | We report a measurement of the branching fraction of the decay B-0 ->rho(0)pi(0), using 386x10(6) B (B) over bar pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We detect 51(-13)(+14) signal events with a significance of 4.2 standard deviations, including systematic uncertainties, and measure the branching fraction to be B(B-0 ->rho(0)pi(0))=(3.12(-0.82)(+0.88)(stat)+/- 0.33(syst)(-0.68)(+0.50)(model))x10(-6). We also perform the first measurement of direct CP violating asymmetry in this mode. |
