DM production mechanisms
Graciela Gelmini, Paolo Gondolo
TL;DR
This paper reviews how dark matter particles, especially WIMPs, are produced in the early Universe across different cosmological models, highlighting mechanisms in both standard and non-standard scenarios.
Contribution
It provides a comprehensive overview of dark matter production mechanisms, emphasizing the role of WIMPs in various cosmological contexts.
Findings
Different production mechanisms are viable in standard and non-standard cosmologies.
WIMPs remain a leading candidate for dark matter due to their production properties.
The review clarifies the impact of early Universe conditions on dark matter abundance.
Abstract
We review the mechanism of production of dark matter particles in the early Universe, both in standard and non-standard pre-Big Bang Nucleosynthesis cosmologies. We concentrate mostly on the production of WIMPs.
