# Dark matter reflection of particle symmetry

## TL;DR

This paper explores how particle symmetries and early Universe phase transitions influence the variety and stability of dark matter candidates, including multicomponent and topological defect scenarios.

## Contribution

It introduces a comprehensive framework linking particle symmetries, phase transitions, and dark matter diversity, emphasizing multicomponent and topological defect candidates.

## Key findings

- Multiple dark matter candidates arise from new symmetries.
- Symmetry breaking patterns lead to topological defects.
- Early Universe phase transitions extend dark matter possibilities.

## Abstract

In the context of the relationship between physics of cosmological dark matter and symmetry of elementary particles a wide list of dark matter candidates is possible. New symmetries provide stability of different new particles and their combination can lead to a multicomponent dark matter. The pattern of symmetry breaking involves phase transitions in very early Universe, extending the list of candidates by topological defects and even primordial nonlinear structures.
