Kinetic and Magnetic Mixing with Antisymmetric Gauge Fields

TL;DR

This paper introduces a general framework for coupling antisymmetric gauge fields, explores magnetic mixing effects leading to millicharges, and discusses extensions to higher monopoles and dark matter models with massless antisymmetric fields.

Contribution

It develops a novel procedure for coupling antisymmetric gauge fields and analyzes magnetic mixing effects, extending previous models to include higher monopoles and dark matter scenarios.

Findings

Magnetic mixing can induce millicharges in hidden sectors.

Extension to higher order monopoles is feasible.

Massless antisymmetric fields can serve as dark matter candidates.

Abstract

A general procedure to describe the coupling $U_A (1) \times U_B (1)$ between antisymmetric gauge fields is proposed. For vector gauge theories the inclusion of magnetic mixing in the hidden sector induces millicharges -- in principle -- observable. We extend the analysis to antisymmetric fields and the extension to higher order monopoles is discussed. A modification of the model discussed in \cite{Ibarra} with massless antisymmetric fields as dark matter is also considered and the total cross section ratio are found and discussed.
