CP ASYMMETRIES OF B→ ΦK~0 AND B → η′K_S DECAYS IN SUSY MODELS

摘要

CP asymmetries of B → ΦK and B → η~((′)) K modes are analyzed in the QCD improved factorization framework. The phenomenological parameters are determined from the global fit for the available B → PP and VP modes (without the subprocess b → sss). The possible deviation of sin(2Φ_1)_(ΦK~0, η′K_s) from sin(2Φ_1)_(J/ΨK_s) and the large branching ratio for B~± → η′K~± can be simultaneously explained in the context of R-parity conserving SUGRA models and R-parity violating SUSY models.
