Why it is here

Shows that a low reheating temperature can loosen the event's apparent one-to-one link between particle mass and scattering rate.

Machine-assisted summary

The authors reproduce the candidate with endothermic pseudo-Dirac dark matter made by freeze-in after low-temperature reheating, whose extra cosmological parameter opens a continuous range of masses, splittings, and cross sections beyond the thermal benchmark.
