CP asymmetry in B \to phi K_S in a SUSY SO(10) GUT

Abstract

We study the $B\to \varphi K_S$ decay in a SUSY SO(10) GUT. We calculate the mass spectrum of sparticles for a given set of parameters at the GUT scale. We complete the calculations of the Wilson coefficients of operators including the new operators which are induced by NHB penguins at LO using the MIA with double insertions. It is shown that the recent experimental results on the time-dependent CP asymmetry $S_{\varphi K}$ in $B\to \varphi K_S$, which is negative and can not be explained in SM, can be explained in the model where there are flavor non-diagonal right-handed down squark mass matrix elements of 2nd and 3rd generations whose size satisfies all relevant constraints from known experiments ($\tau \to \mu \gamma$, $B\to X_S\gamma ,B_s\to {\mu }^{+}{\mu }^{-},B\to X_s{\mu }^{+}{\mu }^{-},B\to X_{s}g,\Delta M_s$, etc.). At the same time, the branching ratio for the decay can also be in agreement with experimental measurements.
