[en] We study an energy-scale dependence of the lepton flavor-mixing matrix in the minimal supersymmetric standard model with the effective dimension-five operators, which give Majorana masses of neutrinos. We analyze the renormalization group equations of the coefficients (κ_ij) of these effective operators under an approximation that neglects terms of order κ². We find that only n_g-1 (where n_g is the generation number) real independent parameters in the lepton flavor-mixing matrix depend on the energy scale. In particular, all the phases in κ are scale-independent. (orig.)
