Abstract

We present a measurement of the time-dependent CP-violating asymmetries in B0→K*0γ(K*0→KS0π0) decays based on 124×106 Υ(4S)→BB̅ decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at the Stanford Linear Accelerator Center. In a sample containing 105±14 signal decays, we measure SK*γ=0.25±0.63±0.14 and CK*γ=-0.57±0.32±0.09, where the first error is statistical and the second, systematic.
