来自ABE的强耦合的Konishi

Konishi at strong coupling from ABE

Adam Rej, Fabian Spill

摘要:

本文从渐近Bethe方程出发,解析地导出了强耦合下平面N=4规范理论中Konishi算子的标度维数。前两个主导项与最近的弦计算和TBA方程的数值分析结果一致。在第三阶,我们发现伪对数的耦合常数,这应该是缺席的任何有限的平面N=4 SYM理论的反常维数。这一项的消除将为最近提出的平面AdS/CFT对应的TBA方程组提供强耦合的重要测试。

英文摘要:

In this letter, we derive analytically the scaling dimension of the Konishi operator in planar N=4 gauge theory at strong coupling from the asymptotic Bethe equations. The first two leading terms agree with the recent string computation and numerical analysis of TBA equations. At the third order we find spurious logarithm of the coupling constant, which should be absent in the anomalous dimension of any finite operator of planar N=4 SYM theory. Showing the cancelation of this term would provide an important test at strong coupling for the recently proposed sets of TBA equations for planar AdS/CFT correspondence.
