我们使用全息技术来计算属于守恒当前超多重态的算子的两点函数，该算子在强耦合下打破超对称性的理论中。这些是必须在规范中介模型中计算的相关量，以确定标准模型 (SSM) 超对称扩展中的软谱。这种全息方法可用于不同的引力背景，但为了明确起见，这里我们重点关注渐近 AdS 背景。在提出总体框架之后，我们将我们的公式应用于两个明确的例子，这两个例子的不同之处在于 SSM 高吉诺的性质，它们具有狄拉克或马约拉纳质量，分别对应于保持或破坏 R 对称性的模型。
We use holographic techniques to compute two-point functions of operators belonging to a conserved current supermultiplet in theories which break supersymmetry at strong coupling. These are the relevant quantities one has to compute in models of gauge mediation to determine the soft spectrum in supersymmetric extensions of the Standard Model (SSM). Such holographic approach can be used for diverse gravitational backgrounds, but here we focus, for definiteness, on asymptotically AdS backgrounds. After presenting the general framework, we apply our formulas to two explicit examples which differ by the nature of the SSM gauginos, which have Dirac or Majorana masses, corresponding to models that respectively preserve or break R-symmetry.
