| 英文摘要 | We show that with a good fit to the muon g - 2 constraint, the CP asymmetry can be as large as 25% (15%) for B-d(0) --> tau + tau(-) d (B-d(0) --> mu(+)mu(-)) in SUGRA models with nortuniversal gaugino masses and MSSM. If tau events indentified at B factories the d CP asymmetry in B-d(0) --> tau(+)tau(-) can be a powerful probe on physics beyond SM. An interesting case is that new physics gives a d prediction on the branching ratio which is still in the uncertain region of the SM prediction. The CP asymmetry for B-d(0) --> 1(+)1(-) in this case can still reach 20%. So it is powerful to shed light on physics beyond SM while the CP asymmetry of b --> sy 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.
