When direct detection constrains reheating temperature: freeze-in with stronger couplings and inflaton-seeded freeze-in

Xavier Bertou, Olivier Deligny, Mathieu Gross +2

Recent results from the DAMIC-M and PandaX collaborations have excluded the standard freeze-in production of dark matter for masses in the range $3~\mathrm{MeV} \lesssim m_χ\lesssi…
