Abstract We consider the expectation value of Wilson lines in two defect versions of N = 4 SYM, both with supersymmetry completely broken, where one is described in terms of an integrable boundary state, the other one not. For both cases, imposing a certain double scaling limit, we find agreement to two leading orders between the expectation values calculated from respectively the field theory- and the string theory side of the AdS/dCFT correspondence.

AdS/dCFT 中的威尔逊线

摘要 我们考虑了在 N = 4 SYM 的两个缺陷版本中威尔逊线的期望值，这两个版本都完全打破了超对称性，其中一个用可积边界状态来描述，另一个不是。对于这两种情况，施加一定的双标度限制，我们发现分别从 AdS/dCFT 对应的场论和弦论方面计算出的期望值之间的两个主要阶数是一致的。
