Neutrino Masses as a Key to New Physics
Marco Drewes, Michele Lucente

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

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, 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.
