AdS/CFT散射矩阵的通用模块

Universal blocks of the AdS/CFT Scattering Matrix

Gleb Arutyunov, Marius de Leeuw, Alessandro Torrielli

摘要:

我们确定某些块的S-矩阵描述的散射的束缚态的AdS 5 × S5超弦,允许在通用的R-矩阵的杨双表示。对于这些情况下,我们使用的公式Drinfeld的第二次实现的Yangian在任意的束缚态表示,以获得相应的R-矩阵的显式表达式。然后,我们表明,这些表达式与先前获得的S-矩阵块完全匹配。

英文摘要:

We identify certain blocks in the S-matrix describing the scattering of bound states of the AdS5 x S5 superstring that allow for a representation in terms of universal R-matrices of Yangian doubles. For these cases, we use the formulas for Drinfeld's second realization of the Yangian in arbitrary bound-state representations to obtain the explicit expressions for the corresponding R-matrices. We then show that these expressions perfectly match with the previously obtained S-matrix blocks.
