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 …
Physics at HERA II
W. Buchmüller
Deep inelastic electron proton scattering at HERA II will allow precise studies of QCD and stringent tests of physics beyond the standard model. We discuss these two aspects of DIS…
CP Violation, Neutrino Mixing and the Baryon Asymmetry
W. Buchmuller, D. Wyler
We study neutrino masses and mixings based on the simplest SO(10) mass relations and the seesaw mechanism. We find that the requirement of large neutrino mixings determines the rel…
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…
Spectator processes and baryogenesis
W. Buchmüller, M. Plümacher
Spectator processes which are in thermal equilibrium during the period of baryogenesis influence the final baryon asymmetry. We study this effect quantitatively for thermal leptoge…
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…
