Evidence of B0 --> rho0 pi0
J. Dragic, T. Gershon
Abstract
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.
