Abstract

Our recent works [1], [2] revisit the proof of chiral symmetry breaking in the confining regime of four-dimensional QCD-like theories, i.e.

S U (N_{c})

gauge theories with

N_{f}

flavors of vectorlike quarks in the fundamental representation. The analysis relies on the structure of ‘t Hooft anomaly matching and persistent mass conditions for theories with same

N_{c}

and different

N_{f}

. In this paper, we work out concrete examples with

N_{c} = 3

and

N_{c} = 5

to support and elucidate the results of [1], [2]. Within the same examples, we also test some claims made in earlier works.

用类量子cd理论中的异常匹配证明手性对称性突破：一个例子

我们最近的工作[1]，b[2]重新审视了在四维类qcd理论的限制域中手性对称性破缺的证明，即在基本表示中具有Nf类矢量夸克的SU（Nc）规范理论。该分析依赖于相同Nc和不同Nf的理论的t - Hooft异常匹配结构和持续质量条件。本文通过Nc=3和Nc=5的具体算例来支持和阐明[1]，[2]的结果。在相同的示例中，我们还测试了早期作品中的一些声明。

期刊介绍： Nuclear Physics B focuses on the domain of high energy physics, quantum field theory, statistical systems, and mathematical physics, and includes four main sections: high energy physics - phenomenology, high energy physics - theory, high energy physics - experiment, and quantum field theory, statistical systems, and mathematical physics. The emphasis is on original research papers (Frontiers Articles or Full Length Articles), but Review Articles are also welcome.
