ABJM理论中的精确大R荷关联函数

Exact Large R-charge Correlators in ABJM Theory

Tanay K. Dey

摘要:

在ABJM理论中构造了一类由Schur多项式给出的算子。通过计算有限$N$上的两个点函数,我们确定了这类算子在自由域极限上是对角的。我们还计算了零耦合极限下的精确三点和多点关联函数。最后,我们考虑了一个特殊的非平凡的背景所产生的运营商与$R$ -收费$O(N^2$。我们表明,非平面的修正(这不能再被忽略,即使在大$N$),可以进行图形化,以给出一个$1/(N+M)$扩展在此背景下计算的标量。

英文摘要:

We construct a class of operators, given by Schur polynomials, in ABJM theory. By computing two point functions at finite $N$ we confirm these are diagonal for this class of operators in the free field limit. We also calculate exact three and multi point correlators in the zero coupling limit. Finally, we consider a particular nontrivial background produced by an operator with an $R$-charge of $O(N^2$. We show that the nonplanar corrections (which can no longer be neglected, even at large $N$) can be resummed to give a $1/(N+M)$ expansion for correlators computed in this background.
