Abstract

The recent publication of high-precision cosmological data has provided us a standard cosmological model. In this model, ~25% of all the energy in the universe is in the form of a non-relativistic dark matter, and ~70% in the form of of a dark energy. The line of research that tries to create a link between particle physics and these forms of energy is very wide. This project is intended to study some research lines where this link comes from new physics in the neutrino sector, like sterile neutrinos and non-standard couplings with scalars. (AU)
