Axino warm dark matter and $Ω_b - Ω_{DM}$ coincidence
arXiv:0704.0510 · doi:10.1103/PhysRevD.75.123506
Abstract
We show that axinos, which are dominantly generated by the decay of the next-to-lightest supersymmetric particles produced from the leptonic $Q$-ball ($L$-ball), become warm dark matter suitable for the solution of the missing satellite problem and the cusp problem. In addition, $Ω_b - Ω_{DM}$ coincidence is naturally explained in this scenario.
