Gravitational Waves from Reheating beyond Instantaneous Thermalization
Kyohei Mukaida, Tenta Tsuji
We study gravitational-wave production during perturbative reheating without assuming instantaneous thermalization of the inflaton decay products. The injected energetic particles…

Systematic derivation of the Boltzmann equation for electroweak baryogenesis
Motoi Endo, Yushi Mura, Tenta Tsuji
We derive the Boltzmann equation for electroweak baryogenesis within a field-theoretical framework. We first algebraically solve the Kadanoff--Baym equations by incorporating the e…

Dark Matter Interpretation of the Super-Kamiokande Antineutrino Excess in model
Motoi Endo, Yushi Mura, Tenta Tsuji
Recent Super-Kamiokande analyses of the diffuse supernova neutrino background, based on data across all SK phases, indicate a mild preference over the zero-DSNB hypothesis at the l…
