Quantum corrections to the effective neutrino mass operator in 5D MSSM
Résumé
We discuss in detail a five-dimensional Minimal Supersymmetric Standard Model compactified on S^1/Z_2 extended by the effective Majorana neutrino mass operator. We study the evolution of neutrino masses and mixings. Masses and angles, in particular the atmospheric mixing angle theta_{23}, can be significantly lowered at high energies with respect to their value at low energy.
