SU(5)×U(1)X grand unification with minimal seesaw and Z′-portal dark matter

We propose a grand unified SU(5)×U(1)X model, where the standard SU(5) grand unified theory is supplemented by minimal seesaw and a right-handed neutrino dark matter with an introduction of a global Z2-parity. In the presence of three right-handed neutrinos (RHNs), the model is free from all gauge a...
