Branching Fraction and CP Asymmetries of B0→K0SK0SK0S

Abstract

We present measurements of the branching fraction and time-dependent CP-violating asymmetries in B-0-> (KSKSKS0)-K-0-K-0 decays based on 227x10(6) Upsilon(4S)-> B (B) over bar 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)x10(-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.
