Speaker: Davide Racco (U. Zurich and ETH Zurich) Various production mechanisms for dark matter complement the well-motivated option of freeze-out. The freeze-in scenario is viable for very weakly-coupled particles, which can be looked for in terrestrial experiments. I will discuss how this mechanism is cosmologically viable with respect to the curvature perturbations that it produces …
