Active projects
Neutrinos in the Early Universe
Marco Drewes, Jamie McDonald, Isabel Oldengott

We study the production and interactions of neutrinos in the primordial plasma from first principles of quantum field theory. This includes Standard Model computations such as QED corrections to Neff as well as constraints on new neutrinos species from cosmology and astrophysics.
