具有色单态技术的Technicolor模型及其紫外扩展
Technicolor Models with Color-Singlet Technifermions and their Ultraviolet Extensions
摘要：
我们研究了其中所有的技术费米子是色单态的技术色模型，专注于这些费米子根据技术色规范群的基本表示变换的情况。我们的分析包括推导出的限制弱超荷分配的technifermion和额外的色单态，technisinglet费米子所产生的必要性，避免稳定的束缚态与异国情调的电荷。这些模型的精确电弱约束进行了讨论。我们确定了一些一般性质的扩展的人工色理论包含这些人工色部门。
英文摘要：
We study technicolor models in which all of the technifermions are color-singlets, focusing on the case in these fermions transform according to the fundamental representation of the technicolor gauge group. Our analysis includes a derivation of restrictions on the weak hypercharge assignments for the technifermions and additional color-singlet, technisinglet fermions arising from the necessity of avoiding stable bound states with exotic electric charges. Precision electroweak constraints on these models are also discussed. We determine some general properties of extended technicolor theories containing these technicolor sectors.
