We discuss fermion mass generation in unified models where QCD and technicolor (or any two strongly interacting theories) have their Schwinger–Dyson equations coupled. In this case the technicolor (TC) and QCD self-energies are modified in comparison with the behavior observed in the isolated theories. In these models the pseudo-Goldstone boson masses are much higher than the ones obtained in different contexts, and phenomenological signals, except from a light scalar composite boson, will be quite difficult to be observed at present collider energies. The most noticeable fact of these models is how the mass splitting between the different ordinary fermions is generated. We discuss how a necessary horizontal (or family) symmetry can be implemented in order to generate the mass splitting between fermions of different generations; how the fermionic mass spectrum may be modified due to GUT interactions, as well as how the mass splitting within the same fermionic generation are generated due to electroweak and GUT interactions.A preprint version of the article is available at ArXiv.

在彩色耦合场景中的费米子质量分裂

我们在统一模型中讨论费米子质量的产生，在该模型中QCD和彩色染料（或任何两个强烈相互作用的理论）将其Schwinger-Dyson方程耦合在一起。在这种情况下，与孤立理论中观察到的行为相比，彩色电子（TC）和QCD自能量被修改。在这些模型中，伪金斯敦玻色子质量远高于在不同环境中获得的质量，并且在当前对撞机能量下，很难观测到现象学信号，除了来自轻量级复合玻色子的现象。这些模型最明显的事实是如何在不同的普通费米子之间产生质量分裂。我们讨论了如何实现必要的水平（或族）对称性，以在不同世代的费米子之间产生质量分裂。该文章的预印本可从ArXiv获得。
