Abstract :

Charmless hadronic decays of charged B-meson to the three-body final states  KsKsK+ and  KsKsPi+ mainly proceed via b->s and b->d loop transitions, respectively. These flavor changing neutral current transitions, being suppressed in the standard model (SM),  are interesting as they could be sensitive to possible non-SM contributions.  We present an improved measurement of the branching fraction and direct CP asymmetry of the decay B+ -> KsKsK+ as well as a search for B+ -> KsKsPi+  using a data sample of 711 fb^−1 , which contains  772 × 10^6 BB-bar pairs and was recorded near the Y(4S) resonance with the Belle detector at the KEKB e+ e− collider.
