  If one has Abelian flavor symmetry, $s_R$-$b_R$ mixing could be near maximal.
This can drive a "strange-beauty" squark ($\widetilde{sb}_{1}$) to be rather
light, but still evade the $b\to s\gamma$ constraint. Low energy constraints
imply that all other superpartners are at TeV scale, except for a possibly
light neutralino, $\widetilde \chi_1^0$. Whether light or heavy, the
$\widetilde{sb}_{1}$ can impact on the $B_s$ system: $\Delta m_{B_s}$ and
indirect CP phase, even for $B_s \to \phi\gamma$. Direct search is similar to
usual $\tilde b \to b\widetilde \chi_1^0$, but existing bounds are weakened by
$\widetilde{sb}_{1} \to s\widetilde \chi_1^0$ possibility. All these effects
could be studied soon at the Tevatron.
