Fate of Symmetric Scalar Field
Kyohei Mukaida, Kazunori Nakayama, Masahiro Takimoto
The evolution of a coherently oscillating scalar field with symmetry is studied in detail. We calculate the dissipation rate of the scalar field based on the closed time path…
Scalar Trapping and Saxion Cosmology
Takeo Moroi, Kyohei Mukaida, Kazunori Nakayama +1
We study in detail the dynamics of a scalar field in thermal bath with symmetry breaking potential. In particular, we focus on the process of trapping of a scalar field at an enhan…
Non-Thermal Production of Wino Dark Matter via the Decay of Long-Lived Particles
Takeo Moroi, Minoru Nagai, Masahiro Takimoto
We consider supersymmetric models in which the neutral Wino is the lightest superparticle (LSP), and study the possibility that non-thermally produced Wino plays the role of dark m…
