我们研究了施加条件，即标准模型有效希格斯势应该有两个近似简并的真空，使得我们生活的真空几乎是亚稳的：我们生活的一个真空期望值为246GeV，另一个真空期望值应该是普朗克标度量级的真空期望值。在实验顶夸克质量为173.1+或-4.6GeV的情况下，单边界亚稳性给出了预测的希格斯玻色子质量为121.8+或-11GeV。根据我们1995年的论文，第二极小值必须在普朗克尺度上的要求已经给出了顶夸克质量的173+或-4GeV的预测。
We study imposing the condition that the standard model effective Higgs potential should have two approximately degenerate vacua, such that the vacuum we live in is just barely metastable: the one in which we live has a vacuum expectation value of 246 GeV and the other one should have a vacuum expectation value of the order of the Planck scale. Alone borderline metastability gives, using the experimental top quark mass 173.1+or-4.6 GeV, the Higgs boson mass prediction 121.8+or-11 GeV. The requirement that the second minimum be at the Planck scale already gave the prediction 173+or-4 GeV for the top quark mass according to our 1995 paper.
