• We report a measurement of time-dependent CP violation parameters in B0→KS0ηγ decays. The study is based on a data sample, containing 772×106BB¯ 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 KS0η system up to 2.1 GeV/c2.
