B_s - \bar{B}_s mixing in the MSSM scenario with large flavor mixing in the LL/RR sector

Abstract

We show that the recent measurements of $B_s-{\bar{B}}_s$ mass difference, $\Delta m_s$, by DØ and CDF collaborations give very strong constraints on MSSM scenario with large flavor mixing in the LL and/or RR sector of down-type squark mass squared matrix. In particular, the region with large mixing angle and large mass difference between scalar strange and scalar bottom is ruled out by giving too large $\Delta m_s$. The allowed region is sensitive to the CP violating phases ${\delta }_{L(R)}$. The $\Delta m_s$ constraint is most stringent on the scenario with both LL and RR mixing. We also predict the time-dependent CP asymmetry in $B_s\to \psi \varphi$ decay and semileptonic asymmetry in $B_s\to \ell X$ decay.
