三维N=2超对称规范理论的α函数

The a-function for N=2 supersymmetric gauge theories in three dimensions

J. A. Gracey, I. Jack, C. Poole, Y. Schroder

摘要:

最近,三维可重整理论的候选a-函数的存在被证明是一般理论在领先秩序和标量费米子理论在次领先秩序。在这里,我们通过构造一个N=2的超对称Chern-Simons理论的次领先阶的a-函数来扩展这项工作。α-函数精度的提高需要在四个环上评估潜在的重整化群函数。

英文摘要:

Recently, the existence of a candidate a-function for renormalisable theories in three dimensions was demonstrated for a general theory at leading order and for a scalar-fermion theory at next-to-leading order. Here we extend this work by constructing the a-function at next-to-leading order for an N=2 supersymmetric Chern-Simons theory. This increase in precision for the a-function necessitated the evaluation of the underlying renormalization-group functions at four loops.
