While doing this, it is used the parameters, At , Ab , As, ht, hb, hs.... etc. brought from Grand Unification Theory(GUT) scale to the weak scale by renormalization group equations. Then, fine-tuningfor the allowed regions is calculated. As a result, the lightest Higgs mass, notedparameter spaces with the lowest fine-tuning (the most natural), is calculated. CR - H. Sert, E.
