Abstract

In this Letter, we introduce a one-parameter deformation of two-dimensional quantum field theories generated by a nonanalytic operator that we call Root-TT[over ¯]. For a conformal field theory, the operator coincides with the square root of the TT[over ¯] operator. More generally, the operator is defined so that classically it is marginal and generates a flow that commutes with the TT[over ¯] flow. Intriguingly, the Root-TT[over ¯] flow is closely related to the ModMax theory recently constructed by Bandos, Lechner, Sorokin, and Townsend.

摘要

在本信函中，我们引入了一种由非解析算子生成的二维量子场论的单参数变形，我们将该算子称为Root - TT[上划线]。对于共形场论，该算子与TT[上划线]算子的平方根一致。更一般地，该算子的定义使得在经典情况下它是边缘的，并生成与TT[上划线]流对易的流。有趣的是，Root - TT[上划线]流与Bandos、Lechner、Sorokin和Townsend最近构建的ModMax理论密切相关。
