Abstract

We present a measurement of the time-dependent CP-violating (CPV) asymmetries in B0→K0Sπ0 decays based on 124×106 Υ(4S)→BB⎯⎯⎯ decays collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. In a sample containing 122±16 signal decays, we obtain the magnitudes of the direct CPV asymmetry CK0Sπ0=0.40+0.27−0.28±0.09 and of the CPV asymmetry in the interference between mixing and decay SK0Sπ0=0.48+0.38−0.47±0.06 where the first error is statistical and the second systematic.
