Abstract

We report the observation of charmless hadronic decays of charged B mesons to the final state K+Kπ+. Using a data sample of 347.5fb1 collected at the Υ(4S) resonance with the BABAR detector, we observe 429±43 signal events with a significance of 9.6σ. We measure the inclusive branching fraction B(B+K+Kπ+)=[5.0±0.5(stat)±0.5(syst)]×106. Inspection of the Dalitz plot of signal candidates shows a broad structure peaking near 1.5GeV/c2 in the K+K invariant mass distribution. We find the direct CP asymmetry to be consistent with zero.
