We consider proton decay and $$\mathbf {g_\mu - 2}$$ in flipped SU(5) GUT models. We first study scenarios in which the soft supersymmetry-breaking parameters are constrained to be universal at some high scale Min above the standard GUT scale where the QCD and electroweak SU(2) couplings unify. In this case the proton lifetime is typically > rsim1036 years, too long to be detected in the foreseeable future, and the supersymmetric contribution to $$\mathbf {g_\mu - 2}$$ is too small to contribute significantly to resolving the discrepancy between the experimental measurement and data-driven calculations within the Standard Model. However, we identify a region of the constrained flipped SU(5) parameter space with large couplings between the 10- and 5-dimensional GUT Higgs representations where p → e+π0 decay may be detectable in the Hyper-Kamiokande experiment now under construction, though the contribution to $$\mathbf {g_\mu - 2}$$ is still small. A substantial contribution to $$\mathbf {g_\mu - 2}$$ is possible, however, if the universality constraints on the soft supersymmetry-breaking masses are relaxed. We find a ‘quadrifecta’ region where observable proton decay co-exists with a (partial) supersymmetric resolution of the $$\mathbf {g_\mu - 2}$$ discrepancy and acceptable values of mh and the relic LSP density.
