Renormalizatión group effects on neutrino masses in partial split supersymmetry

Partial Split Supersymmetry with R-parity violation is used to explain neutrino masses and mixings by including one loop corrections to the effective neutrino mass matrix of thc theory.In this work, we study the possible effects of the renormalization group equations (RGE) on neutrino masses, sin ce...
