We present a measurement of the time-dependent CP-violating (CPV) asymmetries in B0→KS0π0 decays based on 124×10^6 Υ(4S)→BB̅ 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 CKS0π0=0.40-0.28+0.27±0.09 and of the CPV asymmetry in the interference between mixing and decay SKS0π0=0.48-0.47+0.38±0.06 where the first error is statistical and the second systematic.

Abstract
We present a measurement of the time-dependent CP-violating (CPV) asymmetries in B0→KS0π0 decays based on 124×10^6 Υ(4S)→BB̅ 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 CKS0π0=0.40-0.28+0.27±0.09 and of the CPV asymmetry in the interference between mixing and decay SKS0π0=0.48-0.47+0.38±0.06 where the first error is statistical and the second systematic.File in questo prodotto:
