Revealing Randall-Sundrum Hidden Valleys
Don Bunk, Jay Hubisz
TL;DR
This paper explores hidden gauge sectors in Randall-Sundrum models, demonstrating how geometric warping connects the standard model to hidden fields and revisiting the electroweak axion model at TeV scales.
Contribution
It introduces a novel framework for hidden gauge symmetries in warped extra dimensions and applies it to a TeV-scale electroweak axion model.
Findings
Hidden gauge sectors can be effectively connected to the standard model via warping.
The electroweak axion model can be realized at TeV scales within this framework.
Geometric warping facilitates new mechanisms for Peccei-Quinn symmetry breaking.
Abstract
We study 5D gauge symmetries in the Randall-Sundrum geometry that are hidden from the standard model through either small 5D gauge coupling, or through vanishing quantum numbers for the standard model fields. Geometric warping of 5D gravity creates a TeV scale bridge from the standard model to the hidden sector gauge fields. We apply these concepts to a revival of the electroweak axion model, in which the dynamics of Peccei-Quinn symmetry breaking occur at the TeV scale.
