Abstract

The branching fractions for charmless decays of B mesons into the three-body final states B0→K+K-K 0 and B+K0sK0s was measured. It was found that the branching fractions and CP asymmetries were extracted in unbinned extended maximum likelihood fits. It was found that the K+K-K0S final state was dominated by a CP-enev component. The contributions from the signal reconstruction efficiency and form the modeling of the efficiency variation over the space was included to measure systematic uncertainities in the branching fraction.
