Revealing Randall-Sundrum Hidden Valleys

Understand

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.
