Dalitz plot analysis of neutral B-meson decays to charged kaon, charged pion, and neutral pion final states

This thesis describes a Dalitz plot analysis of B0 → K+pi-pi 0 decays. The data sample comprises 213 million &Ugr;(4 S) → BB¯ decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at the Stanford Linear Accelerator Center in California (SLAGC). Preliminary results are presented for measurements of the inclusive branching fraction, quasi-two-body fractions and CP-violating charge asymmetries for intermediate states including K*(892)+pi - and rho(770)-K +. Observations of B0 decays to the Kpi S-wave intermediate states, K*0 (1430)+pi- and K*0 (1430)0pi0, are reported. Evidence of the decay B0 → K*(892) 0pi0 is seen. We set tipper limits at 90% confidence level on branching fractions of the nonresonant and other less significant intermediate states.
