摘要:

最近提出的Coleman-Weinberg模型中的多相临界原理可以为电弱尺度和新物理尺度之间的层次关系提供新的解释。当应用于标准模型时,出现了一个和破标不变性的伪戈德斯通玻色子一样轻的希格斯玻色子。两个光场之间被抑制的混合仍然携带着关于大尺度对称性破缺的信息,尽管要进行对数校正。在这项工作中,我们探讨这种情况下,目前的大型强子对撞机的数据和评估未来的轻子和强子对撞机的影响。我们的研究结果表明,多相临界性可以很容易地解释在当前实验中测试的能量尺度上明显缺乏新物理。

英文摘要:

The recently proposed multi-phase criticality principle in Coleman-Weinberg models can provide a new explanation for the hierarchy between the electroweak and new physics scales. When applied to the Standard Model, a Higgs boson as light as the pseudo-Goldstone boson of broken scale invariance occurs. The suppressed mixing between the two light fields still carries information about the large scale of symmetry breaking, albeit up to logarithmic corrections. In this work we probe this scenario with the present LHC data and assess the impact of future lepton and hadron colliders. Our results show that the multi-phase criticality can easily explain the apparent absence of new physics at the energy scales tested in current experiments.
