Abstract

We report measurements of CP violation parameters in B0→KS0π 0γ transitions based on a data sample of 535×106BB̄ pairs collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. One neutral B meson is fully reconstructed in the B0→KS0π0γ mode. The flavor of the accompanying B meson is identified from its decay products. We obtain time-dependent and direct CP violation parameters S and A for a KS0π0 invariant mass up to 1.8GeV/c2 as SKS0π0γ=-0.10±0.31±0. 07 and AKS0π0γ=-0.20±0.20±0.06. For a KS0π0 invariant mass near the K*0(892) resonance, we obtain SK*0γ=-0.32-0. 33+0.36±0.05 and AK*0γ=-0.20±0.24±0.05.
