操作员混合和AdS/CFT correspondence

Operator Mixing and the AdS/CFT correspondence

George Georgiou, Valeria L. Gili, Rodolfo Russo

摘要:

我们提供了一个直接的处方计算规范不变算子之间的混合N=4 SYM。我们的方法是基于超代数对理论态的作用,因此它也可以应用于解决对偶弦描述中的混合问题。作为一个例子,我们专注于超多重包含BMN运营商与两个杂质。在场论方面,我们导出了对最高权态的朴素表达式的主要平面量子修正。然后我们在AdS 5 xS 5弦论的BMN极限中使用相同的公式,导出了2-杂质最高权态的形式。弦的表达式很好地匹配SYM的结果,并提供了一个预测的混合由于高阶量子校正在场论。

英文摘要:

We provide a direct prescription for computing the mixing among gauge invariant operators in N=4 SYM. Our approach is based on the action of the superalgebra on the states of the theory and thus it can be also applied to resolve the mixing in the dual string description. As an example, we focus on the supermultiplet containing the BMN operators with two impurities. On the field theory side, we derive the leading planar quantum corrections to the naive expression of the highest weight state. Then we use the same prescription in the BMN limit of the AdS5xS5 string theory and derive the form of the 2-impurity highest weight state. The string expression matches nicely the SYM result and provides a prediction for the mixing due to higher order quantum corrections in field theory.
