The neutrino masses and the change of allowed parameter region in universal extra dimension models
Shigeki Matsumoto, Joe Sato, Masato Senami +1
Relic abundance of dark matter is investigated in the framework of universal extra dimension models with right-handed neutrinos. These models are free from the serious Kaluza-Klein…
Neutralino Dark Matter in Light Higgs Boson Scenario
Masaki Asano, Shigeki Matsumoto, Masato Senami +1
Phenomenology of neutralino dark matter in the minimal supersymmetric model is discussed for a scenario where the lightest Higgs boson mass is lighter than 114.4 GeV. We show that…
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-…
