Abstract
If one has Abelian flavor symmetry, sR-bR mixing could be near maximal. This can drive a "strange-beauty" squark (sb̃1 to be rather light, but still evade the b → sγ constraint. Low-energy constraints imply that all other superpartners are at TeV scale, except for a possibly light neutralino, Χ̃1 0. Whether light or heavy, the sb̃1 can impact on the Bs system: ΔmBs and the indirect CP phase, even for Bs → Φγ. A direct search is similar to the usual b̃ → bΧ̃10, but existing bounds are weakened by the sb̃1 → sΧ̃10 possibility. All of these effects could be studied soon at the Fermilab of Tevatron. © 2001 The American Physical Society.
