Non-Gaussian isocurvature perturbations in dark radiation
Etsuko Kawakami, Masahiro Kawasaki, Koichi Miyamoto +2
We study non-Gaussian properties of the isocurvature perturbations in the dark radiation, which consists of the active neutrinos and extra light species, if exist. We first derive…

Axino dark matter and baryon number asymmetry from Q-ball decay in gauge mediation
Shinta Kasuya, Etsuko Kawakami, Masahiro Kawasaki
We investigate the Q-ball decay into the axino dark matter in the gauge-mediated supersymmetry breaking. In our scenario, the Q ball decays mainly into nucleons and partially into…
