A concise summary of out‐of‐equilibrium dark matter production during post‐inflationary reheating is presented. We show that the dark matter relic abundance is in general sensitive to the thermalization rate of the inflaton decay products, and the evolution of the temperature of the subsequently thermalized radiation. We discuss how smoking‐gun signals, such as monochromatic neutrinos or gamma‐ray lines, or Lyman‐α data, can help constrain out‐of‐equilibrium DM models.

再热和暗物质生产

简要总结了通货膨胀后再加热过程中不平衡暗物质的产生。我们表明，暗物质残留物的丰度通常对充气子衰变产物的热化速率以及随后的热辐射温度的演变敏感。我们将讨论诸如单色中微子或伽马射线线或莱曼α数据之类的吸烟信号如何能够帮助限制非平衡DM模型。
