Abstract

We report branching fractions and CP asymmetries for B → ηK^* and B → ηρ decays. These results are obtained from a 414 \rm fb^-1 data sample collected at the Υ(4S) resonance, with the Belle detector at the KEKB asymmetric energy e⁺ e^- collider. The branching fractions, in parts per million, of ηK^*0, ηK^*+, ηρ⁰, and ηρ⁺ are 15.9± 1.2 ± 0.9, 19.7^+2.0_-1.9 ± 1.4, 0.84^+0.56_-0.51 ± 0.18, and 4.1^+1.4_-1.3 ± 0.34, respectively. We find no evidence for CP asymmetries in these modes.
