论文摘要
在这封信中，我们介绍了由非分析运算符生成的二维量子场理论的单参数变形，我们将其称为root- $ t \ overline {t} $。对于共形场理论，操作员与$ t \ overline {t} $ operator的平方根相吻合。更一般而言，定义了操作员，以便从经典上讲是边缘的，并生成了通过$ t \ overline {t} $ - 流的通勤。有趣的是，root- $ t \ overline {t} $流与Bandos，Lechner，Sorokin和Townsend最近构建的Modmax理论密切相关。
In this letter we introduce a one-parameter deformation of two-dimensional quantum field theories generated by a non-analytic operator which we call Root-$T \overline{T}$. For a conformal field theory, the operator coincides with the square-root of the $T \overline{T}$ operator. More generally, the operator is defined so that classically it is marginal and generates a flow which commutes with the $T \overline{T}$-flow. Intriguingly, the Root-$T \overline{T}$ flow is closely related to the ModMax theory recently constructed by Bandos, Lechner, Sorokin and Townsend.
