Study of charmless B decays to three-kaon final states

We report on a study of charmless B meson decays to three-kaon final states. The results are obtained with a 78.7 1/fb data sample collected on the Y(4S) resonance by the Belle detector operating at the KEKB asymmetric energy $e^+e^-$ collider. The branching fractions for B decays to three-body K+K+K-, K0K+K-, KsKsK+, and KsKsKs final states are presented. We also make a first attempt to perform an isospin analysis of the three-kaon final states.
