Measurements Of Branching Fraction And Direct CP Asymmetry In B+ -> KsKsK+ And A Search For B+ -> KsKsPi+ At Belle

2019-03-25 Mr. ABDUL BASITH

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.
