Abstract:

We present a measurement of the time-dependent CP-violating asymmetries in

B^0 \to K^{*0}\gamma (K^{*0}\to K_S^0 \pi^0)

decays based on 124 million

\Upsilon(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^{*0}} = 0.25 \pm 0.63 \pm 0.14

and

S_{K^{*0}} = -0.57 \pm 0.32 \pm 0.09

, where the first error is statistical and the second systematic.
