我们计算一圈和两圈的平方发散贡献裸希格斯质量的裸耦合在标准模型。我们近似裸耦合，在紫外cuto尺度下，MS的在相同的规模，这是由两圈重正化群方程的Higgs质量约126 GeV的标准模型评估。我们得到了裸希格斯质量的cuto尺度依赖性，并检查它在哪里变为零。我们发现，当我们采取目前的中心值为顶夸克极质量，173 GeV，裸希格斯质量消失，如果cuto约为10 23 GeV。如果质量小1.3倍，即170 GeV，则尺度可以是
We compute one- and two-loop quadratic divergent contributions to the bare Higgs mass in terms of the bare couplings in the Standard Model. We approximate the bare couplings, dened at the ultraviolet cuto scale, by the MS ones at the same scale, which are evaluated by the two-loop renormalization group equations for the Higgs mass around 126 GeV in the Standard Model. We obtain the cuto scale dependence of the bare Higgs mass, and examine where it becomes zero. We nd that when we take the current central value for the top quark pole mass, 173 GeV, the bare Higgs mass vanishes if the cuto is about 10 23 GeV. With a 1.3 smaller mass, 170 GeV, the scale can be of the order of
