Radiative Screening of Fifth Forces

TL;DR

This paper introduces a symmetron model where fifth force screening occurs via one-loop Coleman-Weinberg symmetry breaking, potentially evading current constraints while allowing observable deviations from general relativity in cold atom experiments.

Contribution

The paper presents a novel symmetron model with loop-level screening of fifth forces, offering a new mechanism to reconcile fifth force theories with experimental constraints.

Findings

Model can evade current fifth force constraints

Potential for observable deviations in cold atom experiments

Screening mechanism operates at one-loop level

Abstract

We describe a symmetron model in which the screening of fifth forces arises at the one-loop level through the Coleman-Weinberg mechanism of spontaneous symmetry breaking. We show that such a theory can avoid current constraints on the existence of fifth forces but still has the potential to give rise to observable deviations from general relativity, which could be seen in cold atom experiments.
