Abstract

We discuss two models with 1 extra CP phase in bsb\leftrightarrow s transition. The CP phase arg(VtsVtb)\arg (V_{t^\prime s}V_{t^\prime b}) with fourth generations, previously ignored, could impact on bs+b\to s\ell^+\ell^-, ΔmBs\Delta m_{B_s} and sin2ΦBs\sin2\Phi_{B_s}, but does not affect EM and strong penguins. With SUSY at TeV scale, a right-handed ``sb~1\widetilde{sb}_{1}'' squark can be driven light by flavor mixing. It does not affect bs+b\to s\ell^+\ell^-, but can generate SϕKS<0S_{\phi K_S} < 0 while giving SηKSsin2ΦBd0.74S_{\eta^\prime K_S} \sim \sin2\Phi_{B_d} \cong0.74. BsB_s mixing and sin2ΦBs\sin2\Phi_{B_s} would likely be large, and SKSπ0γ0S_{K_S\pi^0\gamma}\neq 0 in B0K0γB^0\to K^{*0}\gamma is promising.
