Vanishing dimension five proton decay operators in the SU(5) SUSY GUT

Naoyuki Haba, Toshihiko Ota

We propose a natural framework of SU(5) supersymmetric grand unified theory with the minimal particle contents, which does not contain dimension five proton decay operators. The su…

Breaking of L_mu - L_tau Flavor Symmetry, Lepton Flavor Violation and Leptogenesis

Toshihiko Ota, Werner Rodejohann

A supersymmetric see-saw model obeying the flavor symmetry L_mu - L_tau, which naturally predicts quasi-degenerate neutrinos, is investigated. Breaking of the symmetry is introduce…
