In the absence of any additional assumption it is natural to conjecture that sizable flavor-mixing mass entries, \ensuremathΔm2, may appear in the mass matrices of the scalars of the MSSM, i.e., \ensuremathΔm2=O(m2). This flavor violation can still be reconciled with experiment if the gaugino mass M(1)/(2) is large enough, leading to a gaugino dominance framework (i.e., m(1)/(2)2\ensuremath≫m2), which permits a remarkably model-independent analysis. We study this possibility focusing our attention on the \ensuremathμ\ensuremath→e, \ensuremathγ decay. In this way we obtain very strong and general constraints, in particular, \fracM(1)/(2)2\ensuremathΔm\ensuremath\gtrsim34 TeV. On the other hand, we show that our analysis and results remain valid for values of m2 much larger than \ensuremathΔm2, namely, for \frac\ensuremathΔm2m2\ensuremath\gtrsim\fracm210 TeV2, thus extending enormously their scope of application. Finally, we discuss the implications for superstring scenarios.
