Discussing Cosmic String Configurations in a Supersymmetric Scenario without Lorentz Invariance

TL;DR

This paper investigates cosmic string configurations within a supersymmetric framework that breaks Lorentz invariance, exploring their potential to produce fermionic dark matter and neutral particles with electromagnetic interactions.

Contribution

It introduces a model of cosmic strings in a Lorentz-symmetry breaking scenario and examines their role as sources of fermionic dark matter and neutral particles with magnetic moments.

Findings

Fermionic dark matter particles with mass ~10^{13} GeV could decay into cosmic rays.

Neutral particles may exhibit electromagnetic interactions due to Lorentz-symmetry breaking.

Cosmic strings could serve as sources for both charged and neutral particles with observable consequences.

Abstract

The main goal of this work is to pursue an investigation of cosmic string configurations focusing on possible consequences of the Lorentz-symmetry breaking by a background vector. We analyze the possibility of cosmic strings as a viable source for fermionic Cold Dark Matter particles. Whenever the latter are charged and have mass of the order of $10^{13}GeV$, we propose they could decay into usual cosmic rays. We have also contemplated the sector of neutral particles generated in our model. Indeed, being neutral, these particles are hard to be detected; however, by virtue of the Lorentz-symmetry breaking background vector, it is possible that they may present an electromagnetic interaction with a significant magnetic moment.
