Title: Evidence for C P violation in B + K * ( 892 ) + π 0 from a Dalitz plot analysis of B + K S 0 π + π 0 decays

Abstract

We report a Dalitz plot analysis of charmless hadronic decays of charged B mesons to the final state K 0 Sπ +π 0 using the full BABAR data set of 470.9 ± 2.8 million B¯B events collected at the Υ(4S) resonance. We measure the overall branching fraction and CP asymmetry to be B(B + → K 0π +π 0) = (31.8 ± 1.8 ± 2.1 +6.0 –0.0) × 10 –6 and ACP(B + → K 0π +π 0) = 0.07 ± 0.05 ± 0.03 +0.02 –0.03, where the uncertainties are statistical, systematic, and due to the signal model, respectively. This is the first measurement of the branching fraction for B + → K 0π +π 0. We find first evidence of a CP asymmetry in B + → K*(892) +π 0 decays: ACP(B + → K*(892) +π 0) = –0.52 ± 0.14 ± 0.04 +0.04 –0.02. The significance of this asymmetry, including systematic and model uncertainties, is 3.4 standard deviations. As a result, we also measure the branching fractions and CP asymmetries for three other intermediate decay modes.

abstractNote = {We report a Dalitz plot analysis of charmless hadronic decays of charged B mesons to the final state K0Sπ+π0 using the full BABAR data set of 470.9 ± 2.8 million B¯B events collected at the Υ(4S) resonance. We measure the overall branching fraction and CP asymmetry to be B(B+ → K0π+π0) = (31.8 ± 1.8 ± 2.1+6.0–0.0) × 10–6 and ACP(B+ → K0π+π0) = 0.07 ± 0.05 ± 0.03+0.02–0.03, where the uncertainties are statistical, systematic, and due to the signal model, respectively. This is the first measurement of the branching fraction for B+ → K0π+π0. We find first evidence of a CP asymmetry in B+ → K*(892)+π0 decays: ACP(B+ → K*(892)+π0) = –0.52 ± 0.14 ± 0.04+0.04–0.02. The significance of this asymmetry, including systematic and model uncertainties, is 3.4 standard deviations. As a result, we also measure the branching fractions and CP asymmetries for three other intermediate decay modes.},
