论文摘要
我们研究热遗物冷冻量的一般特性。我们为任意冷冻过程的遗物丰度提供了分析性估计,显示了何时合适的瞬时冻结以及在冷冻速度缓慢时如何对其进行校正。这用于概括与观察到的丰度相匹配的深色母校和耦合之间的关系。结果包含了经过充分研究的特定示例,例如wimps,simps,coannihilation,coscattering,逆衰减和禁止通道,并概括了它们。反过来,这给出了在暗物质质量上绑定的近似扰动单位性,以进行任意热冷冻过程。我们表明,超越了通过暗物质自我净化允许冻结的最大质量(类似Wimp,$ m _ {\ rm dm} \ gg \ gg \ gg \ gg \ gg \ gg \ mathcal {o}(100〜 \ rm rm tev)$)预测,黑物质几乎是变性的状态,并且暗物质是黑物质,而黑物质是可转化的。我们展示了热遗物的冻结如何使深色物质质量达到普朗克量表。
We study the general properties of the freezeout of a thermal relic. We give analytic estimates of the relic abundance for an arbitrary freezeout process, showing when instantaneous freezeout is appropriate and how it can be corrected when freezeout is slow. This is used to generalize the relationship between the dark mater mass and coupling that matches the observed abundance. The result encompasses well-studied particular examples, such as WIMPs, SIMPs, coannihilation, coscattering, inverse decays, and forbidden channels, and generalizes beyond them. In turn, this gives an approximate perturbative unitarity bound on the dark matter mass for an arbitrary thermal freezeout process. We show that going beyond the maximal masses allowed for freezeout via dark matter self-annihilations (WIMP-like, $m_{\rm DM}\gg\mathcal{O}(100~\rm TeV)$) predicts that there are nearly degenerate states with the dark matter and that the dark matter is generically metastable. We show how freezeout of a thermal relic may allow for dark matter masses up to the Planck scale.
