论文摘要
我们认为在树级的四个维度上，在四个维度上考虑了最小A型高旋转重力。我们为该理论提出了新的图形规则，涉及Fronsdal领域和Didenko -vasiliev（DV）粒子 - HS Gravity的“ BPS Black Hole”的线性化版本。这些顶点包括粒子和量规场之间的标准最小耦合，用于HS场的Sleight-Taronna Cubic顶点，以及最近引入的顶点耦合，将两个HS字段耦合到DV粒子。我们展示了如何将这些成分组合起来以复制理论全息双重双重的所有N点功能 - 自由O（n）矢量模型。我们的示意规则在常规的田间理论与弦理论的规则之间插值。我们的构造可以看作是HS代数的批量实现。
We consider minimal type-A higher-spin (HS) gravity in four dimensions, at tree level. We propose new diagrammatic rules for this theory, involving both Fronsdal fields and Didenko-Vasiliev (DV) particles - linearized versions of HS gravity's "BPS black hole". The vertices include a standard minimal coupling between particle and gauge field, the Sleight-Taronna cubic vertex for HS fields, and a recently introduced vertex coupling two HS fields to a DV particle. We show how these ingredients can be combined to reproduce all n-point functions of the theory's holographic dual - the free O(N) vector model. Our diagrammatic rules interpolate between the usual ones of field theory and those of string theory. Our construction can be viewed as a bulk realization of HS algebra.
