Abstract

A simplified way to calculate the two-loop corrections to the renormalization group equations is investigated and applied to two SO(10) axion models. It is found that the grand unification mass scale M_x is reduced by a factor ~ 1.5 – 3. And in both models, there exist solutions with M_x ~ 10¹⁵Gev, corresponding to a proton lifetime when sin² θ_w, α_s and α_e are chosen within the experimental error range.
