Abstract We derive the corrections to the conformal dimensions of twisted Ramond ground states in the deformed two-dimensional N = ( 4 , 4 ) superconformal ( T 4 ) N / S N orbifold theory describing bound states of the D1-D5 brane system in type IIB superstring theory. Our result holds to second order in the deformation parameter, and at the large N planar limit. The method of calculation involves the analytic evaluation of integrals of four-point functions of two R-charged twisted Ramond fields and two marginal deformation operators. We also calculate the deviation from zero, at first order in the considered marginal perturbation, of the structure constant of the three-point function of two Ramond fields and one deformation operator.

变形 D1-D5 SCFT 中的微态重整化

摘要 我们推导出了对变形二维 N = ( 4 , 4 ) 超共形 ( T 4 ) N / SN 轨道理论描述 IIB 型 D1-D5 膜系统束缚态的扭曲拉蒙德基态的共形维数的修正。超弦理论。我们的结果在变形参数中保持二阶，并且在大 N 平面极限处。计算方法包括对两个带 R 电荷的扭曲拉蒙德场和两个边缘变形算子的四点函数积分的解析评估。我们还计算了两个 Ramond 场和一个变形算子的三点函数的结构常数在所考虑的边际扰动中的一阶与零的偏差。
