We analyze the role of the left-left squark mixing in the rare decay within the minimal supersymmetry with a large . A Higgs boson mass of 125 GeV has been taken into account leading to correlation between stop masses and trilinear soft supersymmetry breaking coupling . We find that measurable effects, similar to that of the well known squark mixing terms, are possible for large combined with the off-diagonal -insertions. Precise measurements of the decay rate are expected from the ongoing NA62 experiment at CERN. We emphasize that the effect we present can put certain limits on the left-left flavor changing structure of the squark mass matrix.
