Measurement of Time-dependent CP-violating Asymmetries in B0 -> K*0 gamma (K*0 -> K0_S pi0) Decays

Abstract

We present a measurement of the time-dependent CP-violating asymmetries in $B^0\to K^{\ast 0}\gamma (K^{\ast 0}\to K_S^0{\pi }^0)$ decays based on 124 million ${\rm Y}(4S)\to B^0{\bar{B}}^0$ decays collected with the BaBar detector at the PEP-II asymmetric-energy $B$ Factory at the Stanford Linear Accelerator Center. In a sample containing $105\pm 14$ signal decays, we measure $S_{K^{\ast 0}}=0.25\pm 0.63\pm 0.14$ and $S_{K^{\ast 0}}=-0.57\pm 0.32\pm 0.09$, where the first error is statistical and the second systematic.
