Abstract: 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 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 Didenko-Vasiliev 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 diagrammatic rules of field theory and those of string theory. Our construction can be viewed as a bulk realization of HS algebra.
