Origin and detection of nontopological soliton dark matter

TL;DR

This paper explores the origins and detection methods of nontopological soliton dark matter, which can form through particle fusion or cosmological phase transitions, resulting in large-mass dark matter candidates.

Contribution

It introduces the formation mechanisms of nontopological soliton dark matter and discusses their potential detectability across various search strategies.

Findings

Dark matter can form with masses from TeV to solar mass.

Formation mechanisms include particle fusion and cosmological phase transitions.

Potential targets for detection are identified across multiple search methods.

Abstract

Macroscopic dark matter like nontopological solitons can form either via the fusion and accumulation of free particles or during cosmological phase transitions. Both mechanisms can create dark matter with large masses ranging from TeV to solar mass. This can lead to interesting targets in direct detection, astrophysical, and cosmological searches.
