一类手征规范理论的anomaly方程的非线性解

Integer solutions to the anomaly equations for a class of chiral gauge theories

Alessandro Podo, Filippo Revello

摘要:

我们在一类规范理论中找到了消除局域规范反常的方程的所有整数荷解,这类规范理论通过$G \times U(1)$形式的规范群扩展了标准模型(SM),其中$G$是任意半单紧李群。假设SM费米子在$G \times U(1)$规范相互作用下是中性的,而新的费米子在新的和SM规范群的非平凡表示中变换。我们的分析也是有效的,当后者是嵌入在一个任意的半单紧李群。具有这种结构的理论最近被研究为基于偶然对称性的复合轴子模型,并且可以为轴子质量问题提供场论解决方案。我们将我们的研究结果的情况下,现象学的兴趣,并证明存在的电荷分配与Peccei-Quinn对称性保护到18维。

英文摘要:

We find all the integer charge solutions to the equations for the cancellation of local gauge anomalies in a class of gauge theories which extend the Standard Model (SM) by a gauge group of the form $G \times U(1)$, where $G$ is an arbitrary semisimple compact Lie group. The SM fermions are assumed to be neutral under $G \times U(1)$ gauge interactions, while the new fermions transform in non-trivial representations of both the new and the SM gauge groups. Our analysis is valid also when the latter is embedded in an arbitrary semisimple compact Lie group. Theories with this structure have been recently studied as models of composite axions based on accidental symmetries and can provide a field theory resolution to the axion quality problem. We apply our results to cases of phenomenological interest and prove the existence of charge assignments with Peccei-Quinn symmetry protected up to dimension 18.
