Abstract
We analyze the predictions of the most general version of the supersymmetric minimal seesaw model with only two right-chiral neutrinos, which are degenerate in masses at the scale of Grand Unification. We apply the renormalization group technique to the running of the masses of the right-chiral neutrinos and the neutrino Yukawa couplings and find that thermal leptogenesis can account for the observed baryon asymmetry of the Universe even with a low reheating temperature, allowing to overcome the gravitino problem.
