摘要:

六个维度的SCFT通过RG流网络相互关联。在具有$6d$整体对称性的黎曼曲面上紧化这样的模型,可以得到各种各样的四维理论。这四个维度的模型也与RG流的网络相关。在本文中,我们研究了四维流相关理论的一些例子,可以从六维开始与不同的SCFT连接的$6d$ RG流。我们编译这样的流,$6d\to 6d\to 4d$和$6d\to 4d\to 4d$,在特定的情况下,当六维模型是那些驻留在M5膜探测不同的$A$型奇点的不同顺序之间的字典。我们所研究的流动是由真空期望值(vevs)触发的,在六维对称性下,这些真空期望值被赋予某些算符。我们发现,对于一般的参数选择的不同顺序的流量,$6d\to 6d\to 4d$和$6d\to 4d\to 4d$,涉及紧化不同的黎曼表面的差异是在表面上的穿刺数。

英文摘要:

SCFTs in six dimensions are interrelated by networks of RG flows. Compactifying such models on a Riemann surface with flux for the $6d$ global symmetry, one can obtain a wide variety of theories in four dimensions. These four dimensional models are also related by a network of RG flows. In this paper we study some examples of four dimensional flows relating theories that can be obtained from six dimensions starting with different SCFTs connected by $6d$ RG flows. We compile a dictionary between different orders of such flows, $6d\to 6d\to 4d$ and $6d\to 4d\to 4d$, in the particular case when the six dimensional models are the ones residing on M5 branes probing different $A$-type singularities. The flows we study are triggered by vacuum expectation values (vevs) to certain operators charged under the six dimensional symmetry. We find that for generic choices of parameters the different orders of flows, $6d\to 6d\to 4d$ and $6d\to 4d\to 4d$, involve compactifications on different Riemann surfaces with the difference being in the number of punctures the surface has.
