Gravitino and Goldstino at Colliders
Wilfried Buchmuller, Koichi Hamaguchi, Michael Ratz +1
We consider theories with spontaneously broken global or local supersymmetry where the pseudo-goldstino or the gravitino is the lightest superparticle (LSP). Assuming that the long…
Neutrinos, Grand Unification and Leptogenesis
W. Buchmüller
Data on solar and atmospheric neutrinos provide evidence for neutrino masses and mixings. We review some basic neutrino properties, the status of neutrino oscillations and implicat…
Neutrino Masses in GUTs and the Baryon Asymmetry
W. Buchmüller
We discuss the implications of large neutrino mixings for grand unified theories based on the seesaw mechanism. In SU(5) GUTs large mixings can be accomodated by means of …
Recent Progress in Leptogenesis
W. Buchmüller
After recalling the general virtues of leptogenesis we compare two realizations, Affleck-Dine leptogenesis and thermal leptogenesis, which generically lead to different predictions…
Some aspects of baryogenesis and lepton number violation
W. Buchmüller
The cosmological baryon asymmetry is closely related to neutrino properties due to the non-perturbative sphaleron processes in the high-temperature symmetric phase of the standard…
Elements of Baryogenesis
Wilfried Buchmuller, Stefan Fredenhagen
Basic ingredients of the theory of baryogenesis are reviewed with emphasis on out-of-equilibrium decays of heavy particles. The present use of kinetic theory is explained and some…
