Remarks on the high-energy behaviour of cross-sections in weak-scale string theories
M. Kachelriess, M. Plumacher
We consider the high-energy behaviour of processes involving Kaluza-Klein (KK) gravitons of weak-scale string theories. We discuss how form-factors derived within string theory mod…
Baryon Asymmetry, Lepton Mixing and SO(10) Unification
M. Plumacher
Baryogenesis appears to require lepton number violation. This is naturally realized in extensions of the standard model containing right-handed neutrinos. We discuss the generation…
Baryon Asymmetry, Neutrino Mixing and Supersymmetric SO(10) Unification
M. Plumacher
The baryon asymmetry of the universe can be explained by the out-of-equilibrium decays of heavy right-handed neutrinos. We analyse this mechanism in the framework of a supersymmetr…
Baryon Asymmetry of the Universe and Lepton Mixing
W. Buchmuller, M. Plumacher
Baryogenesis appears to require lepton number violation. This is naturally realized in extensions of the standard model containing right-handed neutrinos. We discuss the generation…
