Supersymmetric unification in the light of neutrino mass

We argue that with the discovery of neutrino mass effects at super-Kamiokande there is a clear logical chain leading from the standard model through the MSSM and the recently developed minimal left right supersymmetric models with a renormalizable see-saw mechanism for neutrino mass to left right symmetric SUSY GUTS: in particular, SO(10) and SU(2)L × SU(2)R × SU(4)c. The progress in constructing such GUTS explicitly is reviewed and their testability/falsifiability by proton decay measurements emphasized.
