Description
We present measurements of branching fractions and charge asymmetries for the decays B→ηK*, where K* indicates a spin 0, 1, or 2 Kπ system. The data sample corresponds to 344x106 BB pairs collected with the BABAR detector at the PEP-II asymmetric-energy e+e- collider at SLAC. We measure the branching fractions (in units of 10-6): B(B0→ηK*0(892))=16.5±1.1±0.8, B(B+→ηK*+(892))=18.9±1.8±1.3, B(B0→η(Kπ)0*0)=11.0±1.6±1.5, B(B+→η(Kπ)0*+)=18.2±2.6±2.6, B(B0→ηK2*0(1430))=9.6±1.8±1.1, and B(B+→ηK2*+(1430))=9.1±2.7±1.4. We also determine the charge asymmetries for all decay modes
