Title: Evidence for CP violation in B+K*(892)+π0 from a Dalitz plot analysis of B+ K S 0 π+π0 decays

Abstract

We report a Dalitz plot analysis of charmless hadronic decays of charged B mesons to the final state KS0π+π0 using the full BABAR data set of 470.9±2.8 million BB events collected at the Υ(4S) resonance. We measure the overall branching fraction and CP asymmetry to be Β(B+→K0π+π0) = (31.8 ± 1.8 ± 2.1 -0.0 +6.0 ) × 10-6 and ACP(B+→K0π+π0) = 0.07 ± 0.05 ± 0.03 -0.03 +0.02 , 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 -0.02 +0.04 . The significance of this asymmetry, including systematic and model uncertainties, is 3.4 standard deviations. 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 KS0π+π0 using the full BABAR data set of 470.9±2.8 million BB events collected at the Υ(4S) resonance. We measure the overall branching fraction and CP asymmetry to be Β(B+→K0π+π0) = (31.8 ± 1.8 ± 2.1-0.0+6.0) × 10-6 and ACP(B+→K0π+π0) = 0.07 ± 0.05 ± 0.03-0.03+0.02, 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 ± 0.04-0.02+0.04. The significance of this asymmetry, including systematic and model uncertainties, is 3.4 standard deviations. We also measure the branching fractions and CP asymmetries for three other intermediate decay modes.},
