Time-Dependent CP-Violating Asymmetry in B^0→p^0γ Decays (2008)

Abstract
We report the first measurement of CP-violation parameters in B^0 → p^0γ decays based on a data sample of 657×10^6B\bar{B} pairs collected with the Belle detector at the KEKB asymmetric-energy e^+e^- collider. We obtain the time-dependent and direct CP-violating parameters, S_p0γ=-0.83±0.65(stat)±0.18(syst) and A_poγ= -0.44±0.49(stat)±0.14(syst), respectively..
