非定域场论中的Higgs机制

The Higgs mechanism in nonlocal field theory

Leonardo Modesto

摘要:

我们提供了一个非定域标量电动力学的例子,它允许同样的希格斯机制在局部场论中如此成功。构造非局部作用量是为了在任何微扰阶下,对于局部理论的微扰都有相同的精确解和相同的运动方程。因此,当EoM中的稳定真空被替换时,在不稳定真空中传播的微扰自由度被重新洗牌,但它们的数量在任何微扰阶次上都不改变,它们的性质与通常的局域理论相同。最后,该理论在量子水平上是超重整化的或有限的。

英文摘要:

We provide an example of nonlocal scalar electrodynamics that allows the same Higgs mechanism so successful in local field theory. The nonlocal action is structured in order to have the same exact solutions and the same equations of motion for perturbations of the local theory, at any perturbative order. Therefore, the perturbative degrees of freedom that propagate in the unstable vacuum are reshuffled when the stable vacuum is replaced in the EoM, but their number does not change at any perturbative order, and their properties are the same like in the usual local theory. Finally, the theory is super-renormalizable or finite at quantum level.
