Abstract

The time-dependent CP-violating (CPV) asymmetries in B0 → KS0π0 decays based on 124×10 6 υ(4S) → BB̄ decays are measured. The asymmetries are collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. The magnitudes of the direct CPV asymmetry and of the CPV asymmetry in the interference between mixing and decay are obtained in a sample containing 122 ± 16 signal decays. It is found that the first error is statistical in nature while the second is systematic.
