Coupling dark energy with Standard Model states

TL;DR

This paper explores how dark energy might interact with Standard Model particles, affecting fundamental couplings, neutrino masses, and potentially unifying dark energy with dark matter, with implications for cosmology and particle physics.

Contribution

It introduces models of dark energy coupling to gauge fields, neutrinos, and the Higgs, providing new theoretical frameworks and potential cosmological solutions.

Findings

Dark energy coupling could cause deviations in nuclear decay laws.

Constraints from weak interactions limit deviations.

A cosmological model unifying dark energy and dark matter is proposed.

Abstract

In this contribution one examines the coupling of dark energy to the gauge fields, to neutrinos, and to the Higgs field. In the first case, one shows how a putative evolution of the fundamental couplings of strong and weak interactions via coupling to dark energy through a generalized Bekenstein-type model may cause deviations on the statistical nuclear decay Rutherford-Soddy law. Existing bounds for the weak interaction exclude any significant deviation. For neutrinos, a perturbative approach is developed which allows for considering viable varying mass neutrino models coupled to any quintessence-type field. The generalized Chaplygin model is considered as an example. For the coupling with the Higgs field one obtains an interesting cosmological solution which includes the unification of dark energy and dark matter.
