Abstract

We report measurements of branching fractions and CP asymmetries for B→ηK* and B→ηρ decays. These results are obtained from a 414fb-1 data sample collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We measure the following branching fractions: B(B0→ηK*0)=(15.2±1.2±1.0) ×10-6 and B(B+→ηK*+)=(19.3-1.9+2.0±1.5)×10-6, where the first error is statistical and the second systematic. We also find a 2.7σ excess in the B+→ηρ+ mode and measure B(B+→ηρ+)=(4.1-1.3+1.4±0.4)×10-6<6.5×10-6 at 90% confidence level. For B0→ηρ0 decays, we determine the upper limit B(B0→ηρ0)<1.9×10-6 at 90% confidence level. The partial rate asymmetries are ACP(ηK*0)=0.17±0.08±0.01, ACP(ηK*+)=0.03±0.10±0.01, and ACP(ηρ+)=-0.04-0. 32+0.34±0.01.

N2 - We report measurements of branching fractions and CP asymmetries for B→ηK* and B→ηρ decays. These results are obtained from a 414fb-1 data sample collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We measure the following branching fractions: B(B0→ηK*0)=(15.2±1.2±1.0) ×10-6 and B(B+→ηK*+)=(19.3-1.9+2.0±1.5)×10-6, where the first error is statistical and the second systematic. We also find a 2.7σ excess in the B+→ηρ+ mode and measure B(B+→ηρ+)=(4.1-1.3+1.4±0.4)×10-6<6.5×10-6 at 90% confidence level. For B0→ηρ0 decays, we determine the upper limit B(B0→ηρ0)<1.9×10-6 at 90% confidence level. The partial rate asymmetries are ACP(ηK*0)=0.17±0.08±0.01, ACP(ηK*+)=0.03±0.10±0.01, and ACP(ηρ+)=-0.04-0. 32+0.34±0.01.
