Branching Fraction and CP Asymmetries of $B^0\to K_S^0{K}_S^0{K}_S^0$

Abstract

We present measurements of the branching fraction and time-dependent CP-violating asymmetries in $B^0\to K_s^0{K}_s^0{K}_s^0$ decays based on 227 million ${\rm Y}(4S)\to B\bar{B}$ decays collected with the BaBar detector at the PEP-II asymmetric-energy $B$ Factory at SLAC. We obtain a branching fraction of $(6.9_{-0.8}^{+0.9}\pm 0.6)\times 10^{-6},$ and CP asymmetries $C=-0.34_{-0.25}^{+0.28}\pm 0.05$ and $S=-0.71_{-0.32}^{+0.38}\pm 0.04,$ where the first uncertainties are statistical and the second systematic.
