Title: Type II seesaw dominance in SO(10)

Grand unified theories where the neutrino mass is given by type II seesaw have the potential to provide interesting connections between the neutrino and charged fermion sectors. We explore the possibility of having a dominant type II seesaw contribution in supersymmetric SO(10). We show that this can be achieved in the model where symmetry breaking is triggered by 54 and 45 dimensional representations, without the need for additional fields other than those already required to have a realistic charged fermion mass spectrum. Physical consequences, such as the implementation of the Bajc, Senjanovic, and Vissani mechanism, the possibility of the fields responsible for type II seesaw dominance being messengers of supersymmetry breaking, and the realization of baryo and leptogenesis in these theories, are discussed.
