Measurement of time-dependent CP asymmetries in B-0 -> K-S(0)eta gamma decays
Original language description
We report a measurement of time-dependent CP violation parameters in B-0 -> K-S(0)eta gamma decays. The study is based on a data sample, containing 772 x 10(6)B(B)over-bar pairs, that was collected at the Upsilon(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) f 0.07(syst) for the invariant mass of the K-S(0)eta system up to 2.1 GeV/c(2).
