局部RG方程的超空间形式

Superspace formulation of the local RG equation

Roberto Auzzi, Boaz Keren-Zur

摘要:

我们提出了超空间制定的本地RG方程,超对称RG流的研究框架中,全纯性和R-对称性的约束是显而易见的。我们推导出与超外尔对称性非临界相关联的相容性条件,并开始研究它们的含义。作为例子,我们推导出一个表达式的a-函数,并提出了一个模拟的a-最大化方程,这是有效的非临界。我们也适用于这种机器的共形流形的研究,并给出了一个简单的证明,这种流形上的度量是卡勒。

英文摘要:

We present the superspace formulation of the local RG equation, a framework for the study of supersymmetric RG flows in which the constraints of holomorphy and R-symmetry are manifest. We derive the consistency conditions associated with super-Weyl symmetry off-criticality and initiate the study of their implications. As examples, we derive an expression for the a-function, and present an analog of the a-maximization equation, which is valid off-criticality. We also apply this machinery to the study of conformal manifolds and give a simple proof that the metric on such manifolds is Kahler.
