Fri Nov 6 2026 11:30 AM: Dark Matter Production in the Early Universe: Advancing the Standard Treatment

Dark matter constitutes about 27% of today's energy density of the Universe, yet its particle nature remains unknown. Its observed abundance provides key guidance, making a precise understanding of how dark matter was produced in the early Universe crucial. In this talk, I will discuss recent progress on both freeze-out and freeze-in scenarios. I will show how bound-state formation can impact dark matter production via freeze-out and how thermal effects from the primordial plasma can significantly alter freeze-in predictions. These effects prove essential for an accurate interpretation of experimental results.
