Title: “Confronting Dark Matter Freeze-In during Reheating with Constraints from Inflation”
Abstract:
I will discuss the production of Dark Matter (DM) in a minimal freeze-inmodel, specifically considering a non-instantaneous reheating phaseafter inflation. I will demonstrate that for low reheating temperatures, bosonic or fermionic reheating from monomial potentials can lead to adifferent evolution in the DM production and hence to distinct predictions for the parent particle lifetime and mass, constrained bylong-lived particle (LLP) searches. I will demonstrate that the extent to which the standard DM freeze-in production can be modified cruciallydepends on the underlying inflationary model. Our findings underscore the impact of the specific dynamics of inflation on DM freeze-inproduction and highlight their importance for the interpretation of collider signatures.
