作为破缺标度不变性的伪Goldstone玻色子的电弱Higgs

Electroweak Higgs as a pseudo-Goldstone boson of broken scale invariance

Robert Foot, Archil Kobakhidze, Raymond R. Volkas

摘要:

我们指出,有可能将电弱希格斯玻色子玻色子与破标不变性的伪戈德斯通玻色子联系起来,从而以一种技术上自然的方式解决等级问题。我们用两个具体的规范模型来说明这个想法。除了与所有当前可用的实验数据一致之外,两个模型都保持了标准模型的预测能力,因为第一个模型在标准模型之外只有一个额外的参数,而第二个模型与标准模型具有相同数量的自由参数。

英文摘要:

We point out that it is possible to associate the electroweak Higgs boson with the pseudo-Goldstone boson of broken scale invariance, thus resolving the hierarchy problem in a technically natural way. We illustrate this idea with two specific gauge models. Besides being consistent with all currently available experimental data, both models maintain the predictive power of the standard model, since the first model has only one additional parameter beyond the standard model, and the second has the same number of free parameters as the standard model.
