Unveiling complex vector dark matter by magnetic field

TL;DR

This paper explores the hypothesis that complex massive vector fields could constitute dark matter, potentially linking primordial magnetic fields to the evolution of vector dark matter condensates in the universe.

Contribution

It introduces a model of vector dark matter with magnetic components and examines classical configurations, connecting dark matter properties to primordial magnetic fields.

Findings

Classical homogeneous configurations with magnetic components are identified.

The model suggests a link between vector dark matter and primordial magnetic fields.

Potential cosmological implications for magnetic field origins are discussed.

Abstract

We discuss the possibility that dark matter is made of a new complex massive vector field with a global $U(1)$-symmetry. The field interacts with the Standard Model via coupling to the gauge field of the hypercharge group. We study classical homogeneous configurations arising in the theory. Some of these configurations include magnetic components of the Standard Model electromagnetic field tensor. This opens a possibility to relate the origin of possible primordial magnetic fields to the cosmological evolution of vector dark matter condensates composed of magnetic bosons.
