Cosmology constraints on Dark Sector models for colliders
Résumé
I discuss ways through which Cosmology can inform searches for Dark Sector models at colliders, most notably the Large Hadron Collider. I focus on two specific examples, namely on the observed dark matter matter abundance in the Universe as predicted in some freeze-in scenarios and on the constraints that primordial nucleosynthesis can place on models involving neutral scalars beyond the Standard Model of particle physics.
