Dark Matter Decoupling from Plasma

Click For Summary
SUMMARY

The discussion centers on the hypothesis that dark matter particles could be composed of the lightest sterile right-handed neutrinos. It emphasizes the necessity for dark matter to decouple from plasma during its formation to avoid significant interactions with regular matter, which is essential for maintaining its "dark" properties. The conversation highlights the fundamental requirement for dark matter candidates to cease interactions with baryonic matter to remain undetectable.

PREREQUISITES
  • Understanding of sterile neutrinos and their properties
  • Familiarity with plasma physics and its role in particle interactions
  • Knowledge of dark matter theories and candidates
  • Basic concepts of particle physics and interactions
NEXT STEPS
  • Research the properties and implications of sterile right-handed neutrinos
  • Study the mechanisms of plasma decoupling in particle physics
  • Explore various dark matter candidates and their interaction models
  • Investigate the role of baryonic matter in the formation of cosmic structures
USEFUL FOR

Astronomers, physicists, and researchers interested in cosmology, particle physics, and the nature of dark matter will benefit from this discussion.

Hello,

I have been reading about how Dark Matter particles might possibly be made up of the lightest sterile right handed neutrino.

I was wondering, why exactly does the dark matter particle have to decouple from the plasma when it is formed?

All dark matter candidates had to stop interacting (significantly) with regular matter at some point, otherwise they would not be dark.
