Description

The nature of Dark Matter is an ongoing and relevant object of study in astroparticle physics. Despite our best efforts to identify its possible particle properties, the results have been null, which has led to a plethora of models describing viable connections to the Standard Model. In particular, loop models of Dark Matter, like the scotogenic model, have received attention in the last decade but their phenomenology in regard to Dark Matter interactions with neutrinos in the Early Universe has not been widely studied. We aim to explore whether parameters of a one-loop model with Scalar Dark Matter-neutrino interactions such as the dark matter mass, the scattering cross-section, and the couplings can be constrained by Early Universe data like the Lyman-alpha forest, Cosmic Microwave Background anisotropies and the Matter Power Spectrum, and give rise to the observed relic abundance.
