Abstract

Abstract: The one loop correction to the Higgs effective potential and the improvement of renormalization group equation in quantum field theory are discussed. These processing method is applied to the minimum supersymmetric model(MSSM). In the framework of MSSM, the limitation of a stable Higgs effective potential on the sensitive parameter tan β is discussed. Using the two loop order numerical solution for the renormalization group equation, the vacuum stability of the Higgs potential is studied under different energy scales. The results show that the behavior of the Higgs potential changes with the increase of the energy scale, but there is no instability as that in the standard model.

Key words: Higgs potential, vacuum stability, renormalization group equation, supersymmetry
