Higgs G-inflation
Kohei Kamada, Tsutomu Kobayashi, Masahide Yamaguchi +1
A new class of inflation models within the context of G-inflation is proposed, in which the standard model Higgs boson can act as an inflaton thanks to Galileon-like non-linear der…
Affleck-Dine baryogenesis with modulated reheating
Kohei Kamada, Kazunori Kohri, Shuichiro Yokoyama
Modulated reheating scenario is one of the most attractive models that predict possible detections of not only the primordial non-Gaussianity but also the tensor fluctuation throug…
Fate of thermal log type Q balls
Takeshi Chiba, Kohei Kamada, Shinta Kasuya +1
We study time evolution of the ball in thermal logarithmic potential using lattice simulations. As the temperature decreases due to the cosmic expansion, the thermal logarithmi…
