Abstract
We measure the time-dependent CP asymmetry in B0→KS0π0γ decays for two regions of KS0-π0 invariant mass, m(KS0π0), using the final BABAR data set of 467×106 BB̄ pairs collected at the PEP-II e+e- collider at SLAC. We find 339±24 B0→K*0γ candidates and measure SK*γ=-0.03±0.29±0.03 and CK*γ=-0. 14±0.16±0.03. In the range 1.1
