Seminar

FIMPs when cosmology meets particle physics

by Laura Lopez Honorez (Universite Libre de Bruxelles)

Australia/Sydney
Description

Feebly interacting dark matter (DM), produced via freeze-in or superWIMP mechanisms, is well known to imprint non-cold DM signatures on cosmological observables, as well as displaced signatures at colliders. In my talk, I will discuss how cosmology and particle physics experiments complementarily help to corner the viable parameter space of such candidates. I will also explore how a modification of early universe cosmology, with a low reheating temperature and a reheating period dominated by an equation of state different from radiation, might affect the overall picture.
