Current experimental data of neutrino oscillation indicates that the self-complementarity can be satisfied within 3σ ranges of each mixing angles. Thus the self-complementarity may be a key to study a flavor physics behind the standard model, and important to discuss its stability. We analyze renormalization group equations in a context of minimal supersymmetric standard model for the self-complementarity. It is seen that one of Majorana phases plays an important role for the stability of self-complementarity. We find some stable solutions against quantum corrections at a low energy. An effective neutrino mass for neutrino-less double beta decay is also evaluated by the use of neutrino parameters giving rise to the stable solutions.Europhysics Letters AssociationJournal Articleapplication/pdfhttp://hdl.handle.net/2115/52067https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/52067/1/EPL101_11001.pdf0295-5075EPL: Europhysics Letters1011110012013-01enginfo:doi/10.1209/0295-5075/101/11001author
