A Cosmological Reconstruction of the Higgs Vacuum Expectation Value

TL;DR

This paper proposes a toy cosmological model where a Higgs-like scalar field causes cosmic acceleration and predicts variations in fundamental constants, linking particle physics with cosmological observations.

Contribution

It introduces a model with a self-interacting scalar field that drives cosmic acceleration and predicts observable variations in the proton-to-electron mass ratio over cosmic time.

Findings

The model predicts a variation in $mma$ consistent with observational data.

Cosmological reconstruction using jerk parameter supports the model.

Comparison with atomic clock data constrains the scalar field dynamics.

Abstract

We present a simple toy model of cosmic acceleration driven purely by a self-interacting scalar field embedded in theory of grand unification. The scalar self-interaction is Higgs-like and provokes a spontaneous symmetry breaking. The coefficient of the quadratic term in the self-interaction potential has an evolution and it leads to a cosmic variation of proton-to-electron mass ratio, $\mu$. We perform a cosmological reconstruction from the kinematic parameter jerk and discuss a few cosmological consequences of the theory. We also compare the theoretically calculated $\mu$ variation with the observations of molecular absorption spectra from Cesium Atomic Clock data.
