论文摘要

我们考虑用于生成暗物质的通用冻结过程,以及随之而来的标准模型流体的重新热度。我们发现,暗物质在当前观察值探测的宇宙学量表上继承了标准模型的绝热不均匀性,即在冻结期间是超级摩恩。因此,Freeze-In满足ISO狂热扰动的界限。

We consider generic freeze-in processes for generation of Dark Matter, together with the consequent re-thermalization of the Standard Model fluid. We find that Dark Matter inherits the Standard Model adiabatic inhomogeneities on the cosmological scales probed by current observations, that were super-horizon during freeze-in. Thereby, freeze-in satisfies the bounds on iso-curvature perturbations.
