Aubert, B. et al. (2004) Measurements of CP-Violating Asymmetries in B0→Ks0π0 Decays. Physical Review Letters, 93 (13). p. 131805. ISSN 0031-9007
Abstract

We present a measurement of the time-dependent CP-violating (CPV) asymmetries in B0→KS0π0 decays based on 124×106 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.
