TPPC weekly seminar: Laura Lopez-Honorez - "Feebly interacting dark matter, a Non-cold dark matter candidate"

Wednesday 27 Apr 2022, 12:45 → 13:45 Europe/London

Speaker: Laura Lopez-Honorez, Université Libre de Bruxelles

Title: Feebly interacting dark matter, a Non-cold dark matter candidate 

Abstract: 
Dark matter represents 80% of the matter budget of the Universe and up until now its nature is unknown. I will discuss the feebly interacting massive particle (FIMP) scenario in which case the dark matter abundance is due to freeze-in and superWIMP mechanisms. Despite its feeble coupling to Standard Model particles, the associated dark matter candidate could leave a distinctive imprint in collider experiments, in the form of displaced vertices, as well as on cosmological observables. In my talk I will in particular discuss the "warm dark matter like" cosmology imprint of those  particles and show how cosmology and particle physics experiments nicely interplay to delimit the viable parameter space of FIMPs.
