AdS3xS3xT4超弦理论中的三点函数

Three-point functions in superstring theory on AdS3xS3xT4

Carlos A. Cardona, Carmen A. Núñez

摘要:

在AdS(3)/CFT(2)对应的背景下,我们考虑AdS(3)xS(3)xT(4)上IIB超弦理论的R和NS谱流扇区.我们提出了一个推导的顶点运营商创建光谱流图像的手征初级状态以前提出的文献。我们计算谱流保守的三点函数,涉及这些运营商的领域。利用体到边界字典,我们将结果与对偶共形场论中相应的算符,T(4)的对称乘积轨道进行了比较。在小弦耦合的限制下,所有考虑的情况都一致。

英文摘要:

We consider R and NS spectral flow sectors of type IIB superstring theory on AdS(3)xS(3)xT(4) in the context of the AdS(3)/CFT(2) correspondence. We present a derivation of the vertex operators creating spectral flow images of chiral primary states previously proposed in the literature. We compute spectral flow conserving three-point functions involving these operators on the sphere. Using the bulk-to-boundary dictionary, we compare the results with the corresponding correlators in the dual conformal field theory, the symmetric product orbifold of T(4). In the limit of small string coupling, agreement is found in all the cases considered.
