Axinos as Cold Dark Matter

- Summary
- Subjects
- Metrics

Abstract

We show that axinos produced in the early Universe in the decay of the lightest neutralinos are a natural candidate for cold dark matter. We argue that axinos may well provide the main component of the missing mass in the Universe because their relic density is often comparable with the critical density.
