$λ$ -模型中全回路结果的一种推广方法

A generalized method for all-loop results in $λ$-models

Eftychia Sagkrioti

摘要:

我们计算了单变形和双变形非对称$λ$ -模型中单个电流算符的反常维数。我们的方法使用的耦合空间的基本几何,以及一个辅助组相互作用,它完全从非对称模型在特定的限制,符合重整化群流。我们的结果适用于变形参数的所有阶数和底层流代数的所有阶数。我们专门我们的一般结果,特别感兴趣的几个模型,已建成的文献中,这些异常尺寸是未知的。

英文摘要:

We compute the anomalous dimension of the single current operator in the case of single and doubly deformed asymmetric $λ$-models with a general deformation matrix. Our method uses the underlying geometry of the coupling space, as well as an auxiliary group interaction, which completely decouples from the asymmetric model in a specific limit, consistent with the Renormalization Group flow. Our results are valid to all orders in the deformation parameters and leading order to the levels of the underlying current algebras. We specialize our general result to several models of particular interest that have been constructed in the literature and for which these anomalous dimensions were not known.
