Long-Lived Unstable Superparticles at the LHC
Koji Ishiwata, Takumi Ito, Takeo Moroi
In various models of supersymmetry (SUSY), the lightest superparticle in the minimal SUSY standard model sector, which we call MSSM-LSP, becomes unstable. Then, we may observe the…
Cosmology of Gravitino LSP Scenario with Right-Handed Sneutrino NLSP
Koji Ishiwata, Shigeki Matsumoto, Takeo Moroi
We consider supersymmetric model with right-handed (s)neutrinos where the neutrino masses are purely Dirac-type. We discuss cosmology based on such a scenario, paying particular at…
Gravitino Dark Matter with Weak-Scale Right-Handed Sneutrino
Koji Ishiwata, Shigeki Matsumoto, Takeo Moroi
We consider cosmological implications of supersymmetric models with right-handed (s)neutrinos where the neutrino masses are purely Dirac-type. We pay particular attention to the ca…
Right-Handed Sneutrino as Cold Dark Matter of the Universe
Takehiko Asaka, Koji Ishiwata, Takeo Moroi
We consider the minimal supersymmetric standard model (MSSM) extended by introducing three right-handed (s)neutrinos to account for neutrino masses in the oscillation experiments.…
