Supersymmetric Adjoint SU(5)

Understand

Recently we have proposed a renormalizable grand unified theory, based on the SU(5) gauge symmetry, where the neutrino masses are generated through the type I and type III seesaw mechanisms.

• In this letter we study the supersymmetric version of this theory.
• As in the non-susy version it is possible to generate all fermion masses with the minimal number of Higgses, the theory predicts one massless neutrino and the leptogenesis mechanism can be realized.
• All contributions to the decay of the proton and the properties of neutralinos are discussed.
