(g−2)μ and CP asymmetries in B0d,s→l+l− and b→sγ in SUSY models

We show that with a good fit to the muon g−2 constraint, the CP asymmetry can be as large as 25% (15%) for B0d→τ+τ− (B0d→μ+μ−) in SUGRA models with nonuniversal gaugino masses and MSSM. If tau events indentified at B factories the CP asymmetry in B0d→τ+τ− can be a powerful probe on physics beyond SM. An interesting case is that new physics gives a prediction on the branching ratio which is still in the uncertain region of the SM prediction. The CP asymmetry for B0d→l+l− in this case can still reach 20%. So it is powerful to shed light on physics beyond SM while the CP asymmetry of b→sγ in this case can only reach 2% at most which is too small to draw a definite conclusion on new physics effects at B factories.
