Abstract

We report the first measurement of time-dependent CP asymmetry in B0→KS0ρ0γ decays based on 657×106 BB̄ pairs collected with the Belle detector at the KEKB asymmetric-energy collider. We measure the CP-violating parameter SKS0ρ0γ=0.11±0.33(stat)-0.09+0.05(syst) from a signal of 212±17 events. We also obtain the effective direct CP-violating parameter Aeff=0.05±0.18(stat)±0.06(syst) for mKS0π+π-<1.8GeV/c2 and 0.6GeV/c2<mπ+π-<0.9GeV/c2.
