We consider models where moduli fields are not stabilized and play the role of quintessence. In order to evade gravitational tests, we investigate the possibility that moduli behave as chameleon fields. We find that, for realistic moduli superpotentials, the chameleon effect is not strong enough, implying that moduli quintessence models are gravitationally ruled out. More generally, we state a no-go theorem for quintessence in supergravity whereby models either behave like a pure cosmological constant or violate gravitational tests

The paper

Original abstract

We consider models where moduli fields are not stabilized and play the role of quintessence. In order to evade gravitational tests, we investigate the possibility that moduli behave as chameleon fields. We find that, for realistic moduli superpotentials, the chameleon effect is not strong enough, implying that moduli quintessence models are gravitationally ruled out. More generally, we state a no-go theorem for quintessence in supergravity whereby models either behave like a pure cosmological constant or violate gravitational tests

Naturalness in the Past from a Time-Dependent Supersymmetry Scale
hep-ph 2026-11 conditional novelty 7.0 of 10

A time-dependent SUSY-breaking scale from a rolling no-scale modulus can allow light early-universe superpartners and heavy present-day superpartners while satisfying precision constraints.
Everything You Always Wanted To Know About The Cosmological Constant Problem (But Were Afraid To Ask)
astro-ph.CO 2012-05 accept novelty 3.0 of 10

Using Lorentz-invariant dimensional regularization, the Standard Model vacuum energy is about 10^8 GeV^4, roughly 54 orders above the critical density, not the 122 orders usually quoted from a sharp cutoff.
Varying constants, Gravitation and Cosmology
astro-ph.CO 2010-09 accept novelty 2.0 of 10

The review argues that testing the constancy of the fundamental constants is a direct test of local position invariance and the universality of free fall, and catalogues every current observational constraint on such drift.

The existence of chameleons [ref] could support the accelerating expansion of the universe (as components of dark energy) and the time evolution of the fine structure constant.

Constraints on scalar coupling to electromagnetism · Constraints on Chameleons · 0.87
The first was that of Brax & Martin [ref] who constructed a general framework within $𝒩=1$ supergravity where supersymmetry breaking in a hidden sector can generate non-supersymmetric corrections to the scalar potential for an arbitrary number of dark sector fields and induce a coupling between these fields to the minimum supersymmetric standard model (MSSM).
