Neutrino Masses and Lepton-flavor-violating $\tau$ Decays in the Supersymmetric Left-right Model

Understand

In the supersymmetric left-right model, the light neutrino masses are given by the Type-II seesaw mechanism.

• A duality property about this mechanism indicates that there exist eight possible Higgs triplet Yukawa couplings which result in the same neutrino mass matrix.
• In this paper, We work out the one-loop renormalization group equations for the effective neutrino mass matrix in the supersymmetric left-right model.
• The stability of the Type-II seesaw scenario is briefly discussed.
