An efficient renormalization group improved implementation of the MSSM effective potential

Abstract

In the context of MSSM, a novel improving procedure based on the renormalization group equation is applied to the effective potential in the Higgs sector. We focus on the one-loop radiative corrections computed in Landau gauge by using the mass independent renormalization scheme $\overline{DR}$. Thanks to the decoupling theorem, the well-known multimass scale problem is circumvented by switching to a new effective field theory every time a new particle threshold is encountered. We find that, for any field configuration, there is a convenient renormalization scale ${\tilde{Q}}^{\ast }$ at which the loop expansion respects the perturbation series hierarchy and the theory retains the vital property of stability.
