摘要：

The minimal supersymmetric extension of the standard model with large tan beta and heavy squarks (M-q greater than or similar to 1 TeV) is a theoretically well-motivated and phenomenologically interesting extension of the standard model. This scenario naturally satisfies all the electroweak precision constraints and, in the case of not too heavy slepton sector (M-center dot less than or similar to 0.5 TeV), can also easily accommodate the (g-2)(mu) anomaly. Within this framework nonstandard effects could possibly be detected in the near future in a few low-energy flavor violating observables, such as B(B ->tau nu), B(B-s,B-d ->center dot(+)center dot(-)), B(B -> X-s gamma), and B(mu -> e gamma). Interpreting the (g-2)(mu) anomaly as the first hint of this scenario, we analyze the correlations of these low-energy observables under the additional assumption that the relic density of a binolike lightest supersymmetric particle accommodates the observed dark-matter distribution.
