利用重整化群方程的分析方法，研究了μ问题可解的额外U（1）模型中最轻中性Higgs标量的质量上界.为了限制参数空间，我们考虑了辐射对称性破缺的条件和一些唯象约束。我们比较的基础上得到的限制参数空间与下一个最小超对称标准模型（NMSSM）的界限。Higgs手征超多重态间Yukawa耦合的标量势和重整化群方程的性质与Higgs手征超多重态间Yukawa耦合的标量势和重整化群方程的性质有很大的不同。他们可以反映在这个范围内。
The upper mass bound of the lightest neutral Higgs scalar is studied in the $mu$ problem solvable extra U(1) models by using the analysis of the renormalization group equations. In order to restrict the parameter space we take account of a condition of the radiative symmetry breaking and some phenomenological constraints. We compare the bound obtained based on this restricted parameter space with the one of the next to the minimal supersymmetric standard model (NMSSM). Features of the scalar potential and renormalization group equations of the Yukawa couplings among Higgs chiral supermultiplets are rather different between them. They can reflect in this bound.
