Here, we report a measurement of time-dependent CP violation parameters in B0→K0Sηγ decays. The study is based on a data sample, containing 772 × 106B¯B pairs, that was collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e collider. We obtain the CP violation parameters of S = –1.32 ± 0.77(stat) ± 0.36(syst) and A = –0.48 ± 0.41(stat) ± 0.07(syst) for the invariant mass of the K0Sη system up to 2.1 GeV/c2.
