The stability of the standard electroweak vacuum imposes constraints on flavor violating tri-linear soft terms which are comparable to the experimental bounds coming from the absence of the flavor changing neutral currents. Furthermore, contrary to the bounds coming from flavor changing neutral currents, the vacuum stability constraints do not decouple even if the scale of supersymmetry breaking is arbitrarily large. We pinpoint the regions in supersymmetric parameter space, compatible with vacuum stability and the experimental results from the LHC and predict the rates of various lepton flavor violating processes in these regions. Moreover, results coming from demanding the vacuum being meta-stable are juxtaposed to the ones in which vacuum being absolutely stable in nature. We further discuss the dependency on the other related supersymmetric parameters on the result. We assess the prospect for present and future flavor factories while keeping the supersymmetry breaking scale within the LHC reach.
