Lunin-Maldacena背景中巨磁振子的三点关联函数

Three-point Correlation Function of Giant Magnons in the Lunin-Maldacena background

Changrim Ahn, Plamen Bozhilov

摘要:

我们计算了两个有限尺寸(双子)巨磁振子弦态和一个轻磁振子模在卢宁-马尔达塞纳背景中的半经典三点关联函数或结构常数,该模型是γ变形或TsT变换的AdS_5 x S_γ ^[5],与N = 1的超杨-米尔斯理论对偶。我们还证明了结构常数与共形维数之间的一个重要关系,在N = 4的超杨-米尔斯情形下,对于γ变形弦背景仍然成立。

英文摘要:

We compute semiclassical three-point correlation function, or structure constant, of two finite-size (dyonic) giant magnon string states and a light dilaton mode in the Lunin-Maldacena background, which is the γ-deformed, or TsT-transformed AdS_5 x S_γ^5, dual to N = 1 super Yang-Mills theory. We also prove that an important relation between the structure constant and the conformal dimension, checked for the N = 4 super Yang-Mills case, still holds for the γ-deformed string background.
