摘要

我们在微扰理论中考虑了共形场理论中\(T \kern0.9pt\overline{\vphantom{T}\kern6.0pt}\kern-6.9pt T \) -变形的影响。采用一维正则化格式对共形场理论中\(T \kern0.9pt\overline{\vphantom{T}\kern6.0pt}\kern-6.9pt T \) -变形对主场相关函数的贡献进行了微扰计算。在两点相关函数的情况下，给出了域的重整化。

On correlators in \(T\overline{T}\)-deformed conformal field theories

We consider the effect of \(T \kern0.9pt\overline{\vphantom{T}\kern6.0pt}\kern-6.9pt T \)-deformations in conformal field theories within the perturbation theory. A dimensional regularization scheme is used for a perturbative calculation of the contribution of the \(T \kern0.9pt\overline{\vphantom{T}\kern6.0pt}\kern-6.9pt T \)-deformation to the correlation functions of primary fields of conformal field theory. Renormalization of fields in the case of a two-point correlation function is presented.
