Branching fraction and CP asymmetries of B0→KS0KS0KS0

Abstract

We present measurements of the branching fraction and time-dependent CP-violating asymmetries in B0→K0SK0SK0S decays based on 227×106 Υ(4S)→BB decays collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. We obtain a branching fraction of (6.9+0.9−0.8±0.6)×10−6, and CP asymmetries C=−0.34+0.28−0.25±0.05 and S=−0.71+0.38−0.32±0.04, where the first uncertainties are statistical and the second systematic
