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…
Testing the Littlest Higgs Model with T-parity at the Large Hadron Collider
Shigeki Matsumoto, Takeo Moroi, Kazuhiro Tobe
In the framework of the littlest Higgs model with T-parity (LHT), we study the production processes of T-even (T_+) and T-odd (T_-) partners of the top quark at the Large Hadron Co…
Test of Anomaly Mediation at the LHC
Shoji Asai, Takeo Moroi, T. T. Yanagida
In the anomaly-mediated supersymmetry breaking model with the assumption of the generic form of Kahler potential, gauginos are the only kinematically accessible superparticles to t…
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…
Decay of Scalar Condensation in Quantum Field Theory
Shigeki Matsumoto, Takeo Moroi
We consider decay processes of scalar-field condensation in the framework of well-established quantum field theory. We postulate that the quantum state corresponding to the scalar-…
