Axino暖暗物质与$Ω_b - Ω_{DM}$的符合

Axino warm dark matter and $Ω_b - Ω_{DM}$ coincidence

Osamu Seto, Masahide Yamaguchi

摘要:

我们表明,axinos,这是占主导地位的次轻超对称粒子产生的轻子$Q$ -球($L$ -球)的衰变,成为温暖的暗物质适合于失踪的卫星问题和尖点问题的解决方案。此外,在该场景中自然地解释了$Ω_b - Ω_{DM}$重合。

英文摘要:

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.
