一个简单理论的小变形

A Small Deformation of a Simple Theory

Matthew Buican, Takahiro Nishinaka

摘要:

我们研究了最简单的相互作用N=2的SCFT的一个有趣的相关变形-原始的Argyres-Douglas(AD)理论。我们认为,虽然这种变形不是严格意义上的班克斯-扎克斯一样(某些运营商的尺寸变化宏观),有意义上,它构成了一个温和的变形的父AD理论:在“一”异常的确切变化是小的,基本上是饱和的一个循环。此外,IR运营商的贡献,有一个简单的描述,在UV理论再现了一个特定的限制,IR指数到一个非常高的顺序。这些结果使我们得出结论,IR理论是一个相互作用的N=1 SCFT与特别小的“a”和“c”中心荷,这个理论揭示了一些有趣的光的光谱,其AD父母。

英文摘要:

We study an interesting relevant deformation of the simplest interacting N=2 SCFT---the original Argyres-Douglas (AD) theory. We argue that, although this deformation is not strictly speaking Banks-Zaks like (certain operator dimensions change macroscopically), there are senses in which it constitutes a mild deformation of the parent AD theory: the exact change in the "a" anomaly is small and is essentially saturated at one loop. Moreover, contributions from IR operators that have a simple description in the UV theory reproduce a particular limit of the IR index to a remarkably high order. These results lead us to conclude that the IR theory is an interacting N=1 SCFT with particularly small "a" and "c" central charges and that this theory sheds some interesting light on the spectrum of its AD parent.
