PSU(2,2| 4)准经典AdS/CFT的性质

PSU(2,2|4) Character of Quasiclassical AdS/CFT

Nikolay Gromov, Vladimir Kazakov, Zengo Tsuboi

摘要:

我们解决了最近提出的T-和Y-系统(Hirota方程)的AdS/CFT在强耦合标度极限的任意准经典弦状态的精确频谱。相应的T函数是SU(2,2)的超特征标|4)具有最高权的酉表示群,以经典的AdS 5 × S5超弦monodromy矩阵作为群元素。我们提出了一个简洁的第一Weyl型公式,这些字符,并表明,他们正确地再现准经典的单圈量子化的超弦的所有部门的结果,在一些自然的假设。我们还推测了T-函数与量子单值矩阵之间的可能关系。

英文摘要:

We solve the recently proposed T- and Y-systems (Hirota equation) for the exact spectrum of AdS/CFT in the strong coupling scaling limit for an arbitrary quasiclassical string state. The corresponding T-functions appear to be super-characters of the SU(2,2|4) group in unitary representations with a highest weight, with the classical AdS5xS5 superstring monodromy matrix as the group element. We propose a concise first Weyl-type formula for these characters and show that they correctly reproduce the results of quasiclassical one-loop quantization in all sectors of the superstring, under some natural assumptions. We also speculate about possible relation between the T-functions and the quantum monodromy matrix.
