Abstract

Branching fraction measurements of charmless B0K*0h1+h2 (h1,2=K, π) decays are presented, using a data sample of 383×106 Υ(4S)BB¯ decays collected with the BABAR detector at the PEP-II asymmetric-energy B-meson factory at SLAC. The results are B(B0K*0K+K)=(27.5±1.3±2.2)×106, B(B0K*0π+K)=(4.6±1.1±0.8)×106, and B(B0K*0π+π)=(54.5±2.9±4.3)×106. The first errors quoted are statistical and the second are systematic. An upper limit is set for B(B0K*0K+π)<2.2×106 at 90% confidence level. We also present measurements of CP-violating asymmetries for the observed decays.
