Neutrino Masses as a Key to New Physics
Marco Drewes, Jan Hajer

We study the perspectives to probe the origin of neutrino mass with existing or near future experiments. The focus lies on low scale seesaw scenarios involving heavy right handed neutrinos. We are also interested in cosmological implications, such as leptogenesis or connections to Dark Matter.
Neutrinos in the Early Universe
Gilles Buldgen, Marco Drewes

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.
New Paths to Hidden Sectors
Chiara Arina, Marco Drewes, Andrea Giammanco, Jan Hajer

We study the perspectives to search for new long lived particles with existing accelerator facilities. This includes searches for non-standard signatures at the LHC main detectors, fixed target experiments and searches in heavy ion collisions.
Scalar Fields in the Early Universe
Wenyuan Ai, Gilles Buldgen, Marco Drewes

We study the nonequilibrium dynamics of scalar fields in the early universe in the framework of the Schwinger-Keldysh formalism. We are interested in several applications, including inflation, reheating, Dark Matter production and the fate of the Higgs field in the early universe.
Testable Baryogenesis
Marco Drewes

We study the perspectives to probe the origin of baryonic matter in the observable universe with laboratory experiments. Currently the focus lies on low scale leptogenesis scenarios. A key element of our approach lies in the description of CP violating nonequilibrium processes in the early universe from first principles of nonequilibrium quantum field theory.
