We present measurements of the branching fraction and time-dependent CP-violating asymmetries in B0→KS0KS0KS0 decays based on 227×10^6 Υ(4S)→BB̅ decays collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. We obtain a branching fraction of (6.9-0.8+0.9±0.6)×10-6, and CP asymmetries C=-0.34-0.25+0.28±0.05 and S=-0.71-0.32+0.38±0.04, where the first uncertainties are statistical and the second systematic.

Abstract
We present measurements of the branching fraction and time-dependent CP-violating asymmetries in B0→KS0KS0KS0 decays based on 227×10^6 Υ(4S)→BB̅ decays collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. We obtain a branching fraction of (6.9-0.8+0.9±0.6)×10-6, and CP asymmetries C=-0.34-0.25+0.28±0.05 and S=-0.71-0.32+0.38±0.04, where the first uncertainties are statistical and the second systematic.File in questo prodotto:
