Non-relativistic matter and Dark energy in a quantum conformal model

TL;DR

This paper presents a quantum conformal model that naturally results in zero vacuum energy and explains the emergence of non-relativistic matter and dark energy, aligning with observational data.

Contribution

It introduces a generalized standard model with quantum conformal invariance that accounts for dark energy and matter without a cosmological constant.

Findings

Vacuum energy is identically zero in the model

Non-relativistic matter and dark energy emerge naturally

Model aligns with current cosmological observations

Abstract

We consider a generalization of the standard model which respects quantum conformal invariance. This model leads to identically zero vacuum energy. We show how non-relativistic matter and dark energy arises in this model. Hence the model is shown to be consistent with observations.
