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…
Cosmological Baryon Asymmetry and Neutrinos: Baryogenesis via Leptogenesis in Supersymmetric Theories
K. Hamaguchi
Leptogenesis in supersymmetric model is discussed comprehensively and in detail. In the first half, we discuss several leptogenesis mechanisms by the decay of heavy right-handed ne…
Non-thermal Dark Matter from Affleck-Dine Baryogenesis
Masaaki Fujii, K. Hamaguchi
In this talk we discuss the origin and nature of the dark matter in the Affleck-Dine (AD) baryogenesis. The AD baryogenesis via most of the flat directions predict formations of la…
Variations on Supersymmetry Breaking and Neutrino Spectra
F. Borzumati, K. Hamaguchi, Y. Nomura +1
The problem of generating light neutrinos within supersymmetric models is discussed. It is shown that the hierarchy of scales induced by supersymmetry breaking can give rise to sup…
