The minimal supersymmetric extension of the standard model with large tan{beta} and heavy squarks (M{sub q-tilde} > or approx. 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{sub l-tilde} < or approx. 0.5 TeV), can also easily accommodate the (g-2){sub {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{yields}{tau}{nu}), B(B{sub s,d}{yields}l{sup +}l{sup -}), B(B{yields}X{sub s}{gamma}), and B({mu}{yields}e{gamma}). Interpreting the (g-2){sub {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.
