We present measurements of the time-dependent CP-violating asymmetries in B0→KS0KS0KS0 decays based on 384×10^6 Υ(4S)→BB̅ decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We obtain the CP asymmetry parameters C=0.02±0.21±0.05 and S=-0.71±0.24±0.04, where the first uncertainties are statistical and the second systematic. These results are consistent with standard model expectations.

Abstract
We present measurements of the time-dependent CP-violating asymmetries in B0→KS0KS0KS0 decays based on 384×10^6 Υ(4S)→BB̅ decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We obtain the CP asymmetry parameters C=0.02±0.21±0.05 and S=-0.71±0.24±0.04, where the first uncertainties are statistical and the second systematic. These results are consistent with standard model expectations.
