关于二维$\mathcal N=(0,2)$超对称模型中NSVZ $β$函数的注记

Comments on the NSVZ $β$ Functions in Two-dimensional $\mathcal N=(0,2)$ Supersymmetric Models

Jin Chen, Mikhail Shifman

摘要:

重新讨论了二维$\mathcal N=(0,2)$超对称模型中的NSVZ $β$函数。我们构建和讨论了广泛的一类这样的模型使用规范制定。它们都代表了四维${\mathcal N} =1$ Yang-Mills理论的直接类似物,并且没有异常。按照四维空间中同样的推理,我们区分全纯和正则耦合常数。这使我们能够从上面的类中导出所有模型中的精确二维$β$函数。然后,我们比较我们的结果与几个例子已经研究过。

英文摘要:

The NSVZ $β$ functions in two-dimensional $\mathcal N=(0,2)$ supersymmetric models are revisited. We construct and discuss a broad class of such models using the gauge formulation. All of them represent direct analogs of four-dimensional ${\mathcal N} =1$ Yang-Mills theories and are free of anomalies. Following the same line of reasoning as in four dimensions we distinguish between the holomorphic and canonical coupling constants. This allows us to derive the exact two-dimensional $β$ functions in all models from the above class. We then compare our results with a few examples which have been studied previously.
