再论ABJM理论中的大J展开

Large J expansion in ABJM theory revisited

H. Dimov, S. Mladenov, R. C. Rashkov

摘要:

最近,利用AdS/CFT对应计算强耦合下规范理论算符的反常维数取得了进展。在弦论方面,它们是由半经典区域的色散关系给出的。我们重新讨论了$AdS_4\times\mathbb{CP}^3$背景下简单半经典弦色散关系的大电荷展开问题。本文用三种不同的方法计算了任意阶规范理论算符的相应反常维数。虽然三种方法的结果看起来不同,但幂级数展开显示了它们的一致性。

英文摘要:

Recently there has been progress in the computation of the anomalous dimensions of gauge theory operators at strong coupling by making use of AdS/CFT correspondence. On string theory side they are given by dispersion relations in the semiclassical regime. We revisit the problem of large charges expansion of the dispersion relations for simple semiclassical strings in $AdS_4\times\mathbb{CP}^3$ background. We present the calculation of the corresponding anomalous dimensions of the gauge theory operators to an arbitrary order using three different methods. Although the results of the three methods look different, power series expansions show their consistency.
