Holomorphy, triality and non-perturbative beta function in 2d supersymmetric QCD
摘要:
本文研究了由2dN =(0,2)超对称QCD得到的非线性西格玛模型中的RG流。西格玛模型由单个Kahler模量参数化。利用全纯性、试探性和红外不动点的知识,我们确定了它的精确的非微扰beta函数。
英文摘要:
In this paper, we study the RG flow in the non-linear sigma models obtained from a 2d N=(0,2) supersymmetric QCD. The sigma model is parameterized by a single Kahler modulus. We determine its exact non-perturbative beta function using holomorphy, triality and the knowledge of the infra-red fixed point.
