Deconstructing unparticles in higher dimensions

TL;DR

This paper explores unparticles modeled through higher-dimensional deconstruction, demonstrating how scale invariance breaking shifts their spectral function and validating existing spectral function assumptions.

Contribution

It introduces a higher-dimensional deconstruction framework for unparticles and confirms the spectral function shift due to scale invariance breaking, supporting prior models.

Findings

Spectral function shifts with scale invariance breaking

Validation of conventional spectral function ansatz

Framework connects unparticles with higher-dimensional theories

Abstract

Unparticles are realized by deconstruction in higher extra dimensions. It is shown that in this framework when the scale invariance is broken, the corresponding spectral function of the unparticle is shifted by an amount of the breaking scale. The result strongly supports the conventional ansatz for the spectral function of the unparticle in the literature.
