强Yukawa耦合和Top Yukawa耦合中首阶三圈标准模型有效势

Three-loop Standard Model effective potential at leading order in strong and top Yukawa couplings

Stephen P. Martin

摘要:

我发现三圈贡献的有效潜在的标准模型希格斯场,在近似的强和顶部汤川耦合是大的相比,所有其他的耦合,使用修改后的最小减法维正则化。检查遵循规范不变性和重整化群不变性。我还简要地评论了戈德斯通玻色子贡献的有效势所带来的特殊问题,以及希格斯真空期望值,质量和自相互作用耦合之间的关系的结果的数值影响。

英文摘要:

I find the three-loop contribution to the effective potential for the Standard Model Higgs field, in the approximation that the strong and top Yukawa couplings are large compared to all other couplings, using dimensional regularization with modified minimal subtraction. Checks follow from gauge invariance and renormalization group invariance. I also briefly comment on the special problems posed by Goldstone boson contributions to the effective potential, and on the numerical impact of the result on the relations between the Higgs vacuum expectation value, mass, and self-interaction coupling.
