Abstract

We report a search for charmless hadronic decays of neutral B mesons to the final state K+K-π0. The results are based on a 711 fb-1 data sample that contains 772×106 BB̄ pairs, and was collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We find the first evidence for this decay with a significance of 3.5 standard deviations and measure its branching fraction as B(B0→K+K-π0)=[2. 17±0.60(stat)±0.24(syst)]×10-6.
