Dalitz plot analysis of the decay
Here, we report a Dalitz-plot analysis of the charmless hadronic decays of neutral B mesons to K ± π ∓ π 0 . With a sample of ( 231.8 ± 2.6 ) × 10 6 Υ ( 4 S ) → B$$\bar{B}$$ decays collected by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC, we measure the magnitudes and phases of the intermediate resonant and nonresonant amplitudes for B0 and $$\bar{B}$$0 decays and determine the corresponding C P -averaged branching fractions and charge asymmetries. Furthermore, we measure the inclusive branching fraction and C P -violating charge asymmetry and found it to be B ( B 0 → K + π - π 0 ) = ( 35.7$$+2.6\atop{-1.5}$$ + 2.6 - 1.5 ± 2.2 ) × 10 - 6 and A C P = - 0.030 $$+ 0.045\atop{- 0.051}$$ ± 0.055 where the first errors are statistical and the second systematic. We observe the decay B 0 → K * 0 ( 892 ) π 0 with the branching fraction B ( B 0 → K * 0 ( 892 ) π 0 ) = ( 3.6 $$+ 0.7\atop- {0.8}$$ ± 0.4 ) × 10 - 6 . This measurement differs from zero by 5.6 standard deviations (including the systematic uncertainties). The selected sample also contains B 0 → $$\bar{D}$$ 0 π 0 decays where $$\bar{D}$$ 0 → K + π- , and we measure B ( B 0 → $$\bar{D}$$ 0π 0 ) = ( 2.93 ± 0.17 ± 0.18 ) × 10 - 4 .
