Axino warm dark matter and $\Omega_b - \Omega_{DM}$ coincidence

High Energy Physics - Phenomenology 2008-11-26 v2 Astrophysics

Abstract

We show that axinos, which are dominantly generated by the decay of the next-to-lightest supersymmetric particles produced from the leptonic QQ-ball (LL-ball), become warm dark matter suitable for the solution of the missing satellite problem and the cusp problem. In addition, ΩbΩDM\Omega_b - \Omega_{DM} coincidence is naturally explained in this scenario.
