Abstract

We present a measurement of the branching fraction for the Cabibbo- and color-suppressed B0→χc1π0 decay based on a data sample of 657×106BB̄ events collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We observe a signal of 40±9 events with a significance of 4.7σ including systematic uncertainties. The measured branching fraction is B(B0→χc1π0)=(1. 12±0.25(stat)±0.12(syst.))×10-5.
