Measurements of Branching fractions and CP Asymmetries of B→ηh decays

碩士 === 國立臺灣大學 === 物理研究所 === 99 === We present the improved measurements of the B -> ηh branching fraction and CP asymmetries using a data sample of 711 fb−1 that contains 771.58 million BB pairs collected on Υ(4S) resonance with the Belle detector at the KEKB asymmetric energy e+e− collider.
