© 2003, Springer-Verlag, Società Italiana di Fisica. We discuss two models with 1 extra CP phase in b ↔ s transition. The CP phase arg(V t′s V t′b ) with fourth generations, previously ignored, could impact on b → sℓ + ℓ - , Δm Bs and sin 2Φ Bs , but does not affect EM and strong penguins. With SUSY at TeV scale, a right-handed (Formula Presented.) squark can be driven light by flavor mixing. It does not affect b → sℓ + ℓ - but can generate S ϕKS < 0 while giving S η′KS ∼ sin 2Φ Bd ≃ 0.74. B s mixing and sin 2Φ Bs would likely be large, and (Formula Presented.) in B 0 → K ∗0 γ is promising. PACS: 11.30.Hv Flavor symmetries – 12.60.Jv Supersymmetric models – 13.25.Hw Decays of B mesons.
