Dark Energy and the Time Dependence of Fundamental Particle Constants

TL;DR

This paper explores how dark energy could cause fundamental constants and Standard Model parameters to vary over cosmic time, affecting measurements and potentially revealing new physics.

Contribution

It introduces a novel dark energy interpretation linking cosmic time dependence of fundamental constants and Standard Model parameters.

Findings

Significant potential time variation in dark energy measurements.

Smaller variations in Standard Model parameters.

Many effects are rendered invisible due to changing rulers.

Abstract

The cosmic time dependencies of $G$, $\alpha$, $\hbar$ and of Standard Model parameters like the Higgs vev and elementary particle masses are studied in the framework of a new dark energy interpretation. Due to the associated time variation of rulers, many effects turn out to be invisible. However, a rather large time dependence is claimed to arise in association with dark energy measurements, and smaller ones in connection with the Standard Model.
