Time-dependent CP-violating asymmetry in B0→ρ0γ decays

We report the first measurement of CP-violation parameters in B0→ρ0γ decays based on a data sample of 657×106BB̄ pairs collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. We obtain the time-dependent and direct CP-violating parameters, Sρ0γ=-0.83±0.65(stat)±0.18(syst) and Aρ0γ=-0.44±0.49(stat)±0.14(syst), respectively. © 2008 The American Physical Society.
