Unparticles and Holographic Renormalization Group

TL;DR

This paper explores unparticle physics through the holographic renormalization group, analyzing boundary conditions and RG flows for vector unparticles and unfermions from an AdS-CFT perspective.

Contribution

It provides a holographic framework for understanding unparticle interactions, contact terms, and their RG flows, which is a novel approach in unparticle research.

Findings

Identified boundary conditions for vector unparticles and unfermions.

Analyzed the RG flow of contact terms in the holographic context.

Connected unparticle propagators with holographic renormalization techniques.

Abstract

We revisit the unparticle interactions and propagators from the AdS-CFT point of view, and we show how the contact terms and their renormalization group flow appear in the context of the holographic renormalization. We study both vector unparticles and unfermions, uncovering the relevant boundary conditions and renormalization group flows.
