Neutrino Masses and Mixing from Bilinear R-Parity Violation
Fumihiro Takayama, Masahiro Yamaguchi
Neutrino masses and mixing are generated in a supersymmetric standard model when R-parity is violated in bilinear mass terms. The mixing matrix among the neutrinos takes a restrict…

Gravitino Dark Matter without R-parity
Fumihiro Takayama, Masahiro Yamaguchi
Cosmological issues are examined when gravitino is the lightest superparticle (LSP) and R-parity is broken. Decays of the next lightest superparticles occur rapidly via R-parity vi…
