Measurements of branching fractions and CP-violating asymmetries in B0 → ρ±h∓ decays
Measurements of branching fractions and CP-violating asymmetries in B0→ρ±πplusmn; and ρ-K+ decays are presented. As such, no evidence is found for either mixing-induced CP violation in the time-dependent asymmetry of B0→ρ±π± decays, or direct CP violation in B0→ρ-K+. The measurement of direct CP violation is found to be consistent with zero within 2.0 standard deviations, when both statistical and systematic errors are taken into account.
