我们研究的规范依赖的下限希格斯玻色子质量的要求，即电弱真空是全球最小的有效势。本文研究了一个简单的模型，即在双参数R{sub {xi}，u}规范中耦合手征夸克偶的自发破缺的阿贝尔Higgs模型，并证明了在该模型中得到的Higgs玻色子质量的下界依赖于规范参数的选择.我们讨论的意义，这一结果在标准模型中的计算。{版权} {美国物理学会}
We examine the gauge dependence of lower bounds on the Higgs boson mass obtained from the requirement that the electroweak vacuum be the global minimum of the effective potential. We study a simple model, the spontaneously broken Abelian Higgs model coupled to a chiral quark doublet in a two-parameter R{sub {xi},u} gauge, and demonstrate that the lower bounds on the Higgs boson mass obtained in this model are dependent on the choice of gauge parameters. We discuss the significance of this result for calculations in the standard model. {copyright} {ital 1997} {ital The American Physical Society}
