我们利用KEKB非对称电子对撞机上的贝儿探测器在厄普托（4S）共振时收集的140 fb ^-1数据，首次给出了衰变B 0-> rho 0 pi 0的证据。我们检测到一个显著性为3.5个标准差的信号，测得分支分数为Br（B 0->-rho 0 pi 0）=（5.1 +/- 1.6（stat）+/- 0.9（syst））*10^-6。
We present the first evidence of the decay B0 --> rho0 pi0, using 140fb^-1 of data collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric e+e- collider. We detect a signal with a significance of 3.5 standard deviations, and measure the branching fraction to be Br(B0 ->- rho0 pi0) = (5.1 +/- 1.6(stat) +/- 0.9(syst))*10^-6.
