C3 – Leptogenesis and Dark Matter



Project Leaders

Wilfried Buchmüller (e-mail | group homepage)


Abstract

Leptogenesis relates the origin of matter to CP violating interactions of heavy Majorana neutrinos in the high-temperature phase of the early universe. It is closely related to the nature of dark matter. The goals of the project are the full quantum mechanical description of the nonequilibrium process leading to the matter-antimatter asymmetry, the effect of the reheating process after inflation on the generated asymmetry and signatures of decaying gravitino dark matter in cosmic rays and at the LHC.
