Why it is here

Uses the recoil as a probe of the expansion history before nucleosynthesis rather than only of particle parameters.

Machine-assisted summary

The author fits endothermic freeze-in dark matter to the event during a pre-BBN era of modified cosmic expansion, using the relic abundance together with collider and cosmological bounds to select viable histories.
