Seesaw scale, unification, and proton decay
Abstract
We investigate a simple realistic grand unified theory based on the $SU(5)$ gauge symmetry, which predicts an upper bound on the proton decay lifetime for the channels $$p{\rightarrow}{K}^{+}\overline{{\nu}}$$ and $$p{\rightarrow}{{\pi}}^{+}\overline{{\nu}}$$, i.e., $${\tau}(p{\rightarrow}{K}^{+}\overline{{\nu}}){\lesssim}3.4\times{}{10}^{35}$$ and $${\tau}(p{\rightarrow}{{\pi}}^{+}\overline{{\nu}}){\lesssim}1.7\times{}{10}^{34}\text{ }\text{ }\mathrm{years}$$, respectively. In this context, the neutrino masses are generated through the type I and type III seesaw mechanisms, and one predicts that the field responsible for type III seesaw must be light with a mass below 500 TeV. We discuss the testability of this theory at current and future proton decay experiments.
