Gauge theories in four dimensions can exhibit interesting low energy phenomena, such as infrared enhancements of global symmetry. We explore a class of 4d N $$ \mathcal{N} $$ = 1 gauge theories arising from a construction that is motivated by duality walls in 5d gauge theories. Their quiver descriptions bear a resemblance to 4d theories obtained by compactifying 6d N $$ \mathcal{N} $$ = (1 , 0) superconformal field theories on a torus with fluxes, but with lower number of flavours and different number of gauge singlets and superpotentials. One of the main features of these theories is that they exhibit a flavour symmetry enhancement, and with supersymmetry enhancement for certain models, in the infrared. Properties of the superconformal fixed points of such theories are investigated in detail.

5d规范理论中的对称增强和对偶壁

四个维度的规范理论可以展示有趣的低能量现象，例如全局对称性的红外增强。我们探索了一类 4d N $$ \mathcal{N} $$ = 1 规范理论，这些规范源自一种由 5d 规范理论中的对偶墙激发的结构。他们的箭袋描述与 4d 理论相似，该理论是通过在具有通量的环面上压缩 6d N $$ \mathcal{N} $$ = (1 , 0) 超共形场理论而获得的，但具有较少的风味和不同数量的规范单线态和超电势。这些理论的主要特征之一是它们在红外线中表现出风味对称性增强，并且对于某些模型具有超对称性增强。详细研究了这些理论的超共形不动点的性质。
