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…
A Solution to the Doublet-Triplet Splitting Problem in the Type IIB Supergravity
T. Watari, T. Yanagida
The doublet--triplet mass splitting problem is one of the most serious problems in supersymmetric grand unified theories (GUTs). A class of models based on a product gauge group, s…
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…
Double Inflation in Supergravity and the Boomerang Observations
Toshiyuki Kanazawa, Masahiro Kawasaki, Naoshi Sugiyama +1
One of the biggest mystery of the recent observation of cosmic microwave background anisotropies by the boomerang team is insignificance of the second acoustic peak in the angular…
Prediction of the CP violation in the Phenomenological Quark-Lepton Mass Matrix Approach
M. Fukugita, M. Tanimoto, T. Yanagida
We explore the phenomenological quark-lepton mass matrices, which are devised following the S flavour symmetry principle, yet fully consistent with SU(5) gauge models with the…
