论文摘要
在变形的二维$ \ mathcal n =（4,4）$ super-of-offormal $（\ Mathbb t^4）^n/s_n $ orbifold理论描述IIB类型IIB类型中的D1-D5 Brane系统的结合状态。我们的结果在变形参数和大$ n $ planar限制中保持二阶。计算方法涉及对两个R带电扭曲的Ramond场和两个边缘变形算子的四点函数的积分进行分析评估。我们还计算了两个ramond磁场和一个变形算子的三点函数的结构常数，从考虑到边缘扰动的一阶和一阶计算偏差。
We derive the corrections to the conformal dimensions of twisted Ramond ground states in the deformed two-dimensional $\mathcal N = (4,4)$ superconformal $(\mathbb T^4)^N/S_N$ 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.
