摘要

考虑具有SU(N) M规范群和双基物质的4维$$ \mathcal{N} $$ N = 2超共形颤振理论，在该理论的平面极限下计算了N个重合Wilson环的相关函数。利用这些算子的特定的非扭曲/扭曲组合，并使用超对称局域化，我们能够恢复整个微扰展开，并找到对所有t - Hooft耦合值有效的这些相关器的精确表达式。此外，我们解析导出了相关器的主要强耦合行为，表明它们遵循一个非常简单的规则。我们的分析是由基于摄动级数的一种近似恢复的数值检验来补充的。

Wilson loop correlators at strong coupling in $$ \mathcal{N} $$ = 2 quiver gauge theories

A bstract We consider 4-dimensional $$ \mathcal{N} $$ N = 2 superconformal quiver theories with SU( N ) M gauge group and bi-fundamental matter and we evaluate correlation functions of n coincident Wilson loops in the planar limit of the theory. Exploiting specific untwisted/twisted combinations of these operators and using supersymmetric localization, we are able to resum the whole perturbative expansion and find exact expressions for these correlators that are valid for all values of the ’t Hooft coupling. Moreover, we analytically derive the leading strong coupling behaviour of the correlators, showing that they obey a remarkable simple rule. Our analysis is complemented by numerical checks based on a Padé resummation of the perturbative series.

期刊介绍： The aim of the Journal of High Energy Physics (JHEP) is to ensure fast and efficient online publication tools to the scientific community, while keeping that community in charge of every aspect of the peer-review and publication process in order to ensure the highest quality standards in the journal. Consequently, the Advisory and Editorial Boards, composed of distinguished, active scientists in the field, jointly establish with the Scientific Director the journal''s scientific policy and ensure the scientific quality of accepted articles. JHEP presently encompasses the following areas of theoretical and experimental physics: Collider Physics Underground and Large Array Physics Quantum Field Theory Gauge Field Theories Symmetries String and Brane Theory General Relativity and Gravitation Supersymmetry Mathematical Methods of Physics Mostly Solvable Models Astroparticles Statistical Field Theories Mostly Weak Interactions Mostly Strong Interactions Quantum Field Theory (phenomenology) Strings and Branes Phenomenological Aspects of Supersymmetry Mostly Strong Interactions (phenomenology).
