Supersymmetric seesaw model for the (1+3)-scheme of neutrino masses

F. Borzumati, K. Hamaguchi, T. Yanagida

A four-neutrino spectrum with a sterile neutrino without significant involvement in the atmospheric and solar neutrino oscillation experiments has been recently advocated as the co…

Cosmological Gravitino Problem in Gauge-Mediated Supersymmetry Breaking Models

T. Asaka, K. Hamaguchi, Koshiro Suzuki

We investigate the cosmological gravitino problem in gauge-mediated supersymmetry breaking models, where the gravitino becomes in general the lightest supersymmetric particle (LSP)…
