论文摘要
$ \ mathbb {t}^4 $的对称Orbifold是四个维度的Free Sym的类似物，其对偶的描述是通过在$ {\ rm ADS} _3 \ times {\ rm s} {\ rm S}^3 \ times times \ times \ mathbb {\ mathbb {\ rm s}^3 \ mathbb {tembb {在本文中，我们研究了该精确的ADS/CFT二元性的变形，远离自由点。在对称的Orbifold方面，这相当于从$ 2 $ cycle Twisted部门中扰动该理论。我们确定了双重世界描述中的相应扰动，并表明从这个世界表的角度正确地复制了许多对称Orbifold电流的异常形式的共形尺寸。
The symmetric orbifold of $\mathbb{T}^4$ is the analogue of free SYM in four dimensions, and its dual is described by a tensionless string propagating in ${\rm AdS}_3\times {\rm S}^3 \times \mathbb{T}^4$. In this paper we study the deformation of this exact AdS/CFT duality away from the free point. On the symmetric orbifold side this amounts to perturbing the theory by the exactly marginal operator from the $2$-cycle twisted sector. We identify the corresponding perturbation in the dual worldsheet description, and show that the anomalous conformal dimensions of a number of symmetric orbifold currents are correctly reproduced from this worldsheet perspective.
