Abstract: (Elsevier)
We describe the renormalization group evolution of the scalar mass term in unified theories. There is no fine-tuning problem in renormalization group improved perturbation theory for scalar fields if an appropriate set of short distance parameters is used. The gauge hierarchy problem has two possible issues: it may either be solved by the renormalization group approach itself with a strong scale dependence of the scalar mass, or it is reduced to the question “why is the mass of the scalar doublet normalized at the Planck scale much smaller than the Planck mass?” In the second case, a possible solution of the gauge hierarchy problem refers to a unification with gravity.- RENORMALIZATION GROUP
