集体对称性破缺的紫外完备化算符

Operators in ultraviolet completions for collective symmetry breaking

Nobuhiro Uekusa

摘要:

我们研究了弱耦合规范理论中标量-规范相互作用的拉格朗日项,在紫外动量截断模型中,集体对称性破缺机制保护希格斯质量平方不发生二次发散.我们还提出了一个五维模型,其中的规范对称性破缺是通过与局部规范变换相一致的边界条件实现的。结果表明,标量规范算子在两个模型中不同的平方发散的情况下。

英文摘要:

We investigate the Lagrangian terms of scalar-gauge interactions in a weakly-coupled gauge theory beyond the ultraviolet momentum cutoff of models where the collective symmetry breaking mechanism protects the Higgs mass squared against having quadratic divergence. We also propose a five-dimensional model in which the gauge symmetry breaking is achieved by boundary conditions consistent with local gauge transformations. It is shown that the scalar-gauge operators in the two models differ in the absence of quadratic divergence.
