ABJM理论中拓扑弦的精确结果

Exact Results in ABJM Theory from Topological Strings

Marcos Marino, Pavel Putrov

摘要:

最近,Kapustin,Willett和Yaakov利用局部化技术发现,ABJM理论中威尔逊圈的真空期望值可以用矩阵模型计算。我们表明,这个矩阵模型是密切相关的陈-西蒙斯理论的透镜空间与规范超群。该理论具有一个拓扑弦大N对偶,这使得在大N展开下精确求解矩阵模型成为可能。特别地,我们找到了ABJM理论中1/6 BPS威尔逊圈真空期望值的精确表达式,它是t Hooft参数的函数,在平面极限下也是如此。该表达式给出了弱耦合区和强耦合区之间的精确插值函数。在强耦合的行为是在精确的协议与预测的AdS弦对偶。对于Drukker和Trancanelli最近构造的1/2 BPS威尔逊圈,我们也给出了明确的结果

英文摘要:

Recently, Kapustin, Willett and Yaakov have found, by using localization techniques, that vacuum expectation values of Wilson loops in ABJM theory can be calculated with a matrix model. We show that this matrix model is closely related to Chern-Simons theory on a lens space with a gauge supergroup. This theory has a topological string large N dual, and this makes possible to solve the matrix model exactly in the large N expansion. In particular, we find the exact expression for the vacuum expectation value of a 1/6 BPS Wilson loop in the ABJM theory, as a function of the 't Hooft parameters, and in the planar limit. This expression gives an exact interpolating function between the weak and the strong coupling regimes. The behavior at strong coupling is in precise agreement with the prediction of the AdS string dual. We also give explicit results for the 1/2 BPS Wilson loop recently constructed by Drukker and Trancanelli
