Branching Fraction and CP Asymmetries of B0→K0SK0SK0S

Abstract

We present measurements of the branching fraction and time-dependent C P -violating asymmetries in B 0 → K 0 S K 0 S K 0 S decays based on 227 × 10 6 Υ ( 4 S ) → B ¯¯¯ B 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 C P 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.
