手征技术夸克模型中的125 GeV Higgs

125 GeV Higgs from a chiral-techniquark model

Stefano Di Chiara, Roshan Foadi, Kimmo Tuominen

摘要:

我们考虑强耦合规范理论的自旋零谱。特别是,我们重点讨论了规范动力学外部存在四费米子相互作用时等单重标量共振的动力学质量。这是由动力学电弱对称性破缺的扩展技术框架激发的。应用大- $N$限制,我们总结了所有的领导阶的贡献,并发现修正的质量的等单线标量共振可以很大,潜在地减少其值从${\cal O}(1)$ TeV的观察值为125 GeV。

英文摘要:

We consider the spin-zero spectrum of a strongly coupled gauge theory. In particular, we focus on the dynamical mass of the isosinglet scalar resonance in the presence of a four-fermion interaction external to the gauge dynamics. This is motivated by the extended technicolor framework for dynamical electroweak symmetry breaking. Applying the large-$N$ limit, we sum all the leading-order contributions, and find that the corrections to the mass of the isosinglet scalar resonance can be large, potentially reducing its value from ${\cal O}(1)$ TeV to the observed value of 125 GeV.
