Description
We build a SU(5) model with type-I+III seesaw by introducing a fermion field ${\bf 24}_F$. Under the condition of gauge coupling unification at two-loop level, we scan the parameter space of new particles. We find $M_{\Sigma}$ should be light to increase the scale of $M_{\rm GUT}$. Three new particles satisfy the following mass hierarchy $M_{\Sigma}
