标题： Defining Root-$T\overline{T}$

摘要： 我们给出最近引入的根号$T\bar{T}$算子在具有连续尺度权重谱的一般二维量子共形场论中的暂定定义。该定义假设某些分解性质，并使用施温格参数化来引入平方根。通过显式计算两点和三点关联函数的变化，研究了该算子的性质。 显示英文摘要

摘要： We give a tentative definition of the recently introduced Root-$T\bar{T}$ operator in a generic, two dimensional quantum conformal field theory with continuous spectrum of scaling weights. The definition assumes certain factorization properties and uses Schwinger parametrization to introduce the square root. The properties of the operator thus defined is investigated by explicit computation of variations o two- and three-point correlation functions.
