动力学对称破缺中多相临界态的光希格斯玻色子

Light Higgs boson from multi-phase criticality in dynamical symmetry breaking

Kristjan Kannike, Luca Marzola, Martti Raidal, Alessandro Strumia

摘要:

Coleman-Weinberg机制可以实现动力学对称性破缺的不同阶段。在每一个阶段的标量的组合,对应于伪戈德斯通玻色子的标度不变性,有一个环抑制质量。我们表明,额外的标量,超越了伪戈德斯通玻色子,可以成为光在两个不同的阶段共存的参数空间中的临界点。我们提出了一个最小的实现机制在多标量模型,详细说明如何循环抑制群众和混合可以计算。我们讨论了实现所产生的多相临界性原则及其相关的情况下的希格斯玻色子。

英文摘要:

The Coleman-Weinberg mechanism can realise different phases of dynamical symmetry breaking. In each phase a combination of scalars, corresponding to the pseudo-Goldstone boson of scale invariance, has a loop-suppressed mass. We show that additional scalars, beyond the pseudo-Goldstone bosons, can become light at critical points in the parameter space where two different phases co-exist. We present a minimal implementation of the mechanism in multi-scalar models, detailing how loop-suppressed masses and mixings can be computed. We discuss realisations of the resulting multi-phase criticality principle and its relevance to the case of the Higgs boson.
