In this study, we revisit minimal nonsupersymmetric models of SU(5) grand unification with the type II seesaw mechanism as the origin of neutrino masses. By imposing the requirement of gauge coupling unification and the proton lifetime bounds, we perform a Bayesian fit to obtain quantitative information on the mass scales of the beyond the Standard Model particles. We then investigate lepton-flavor-violating processes induced by the type II scalar triplet and its SU(5) partners, showing that upcoming searches for different lepton-flavor-violating observables can provide additional information on the masses of the new particles and impose nontrivial constraints on neutrino parameters.
We revisit minimal nonsupersymmetric models of SU(5) grand unification with the type II seesaw mechanism as the origin of neutrino masses. Imposing the requirement of gauge coupling unification and the proton lifetime bounds, we perform a Bayesian fit and obtain robust quantitative information on the mass scales of the beyond the Standard Model particles. We then study lepton-flavor-violating processes induced by the type II scalar triplet and its SU(5) partners, showing that the interplay of upcoming searches for different lepton-flavor-violating observables can provide additional information on the masses of the new particles, as well as nontrivial constraints on neutrino parameters.
