The CGF dark matter fluid

TL;DR

This paper introduces a classical SU(2) gauge field solution called the cosmological gauge field (CGF) that acts as dark matter, providing a consistent fluid description and justifying stellar structure models within this framework.

Contribution

It presents a natural, local construction of the CGF, deriving its macroscopic properties and linking it to cosmological and stellar models of dark matter.

Findings

CGF is an irrotational perfect fluid

Provides a global time coordinate and rest frame

Justifies TOV stellar structure solutions for CGF dark matter

Abstract

The cosmological gauge field (CGF) is a classical solution of SU(2)-weak gauge theory oscillating rapidly in time. It is the dark matter driving the CGF cosmology. A general, local, mathematically natural construction of the CGF is given here. The macroscopic properties are derived. The CGF is an irrotational perfect fluid. It provides a synchronized global time coordinate and a global rest frame. There is a conserved number density. The energy density and pressure are related by the same equation of state as derived in the CGF cosmology and used in the TOV stellar structure equations for stars made of CGF dark matter. The present construction justifies the TOV solution. Some possible routes towards testing the theory are suggested at the end.
