Thermal Production of Axions from Heavy Higgs Bosons
Kodai Sakurai, Fuminobu Takahashi
We discuss the thermal production of axions in renormalizable models involving two Higgs doublet fields and a complex singlet field with a global Peccei-Quinn symmetry, i.e.…

Stimulated Emission of Dark Matter via Thermal Scattering: Novel Limits for Freeze-In and eV Cold Dark Matter
Kodai Sakurai, Wen Yin
Recently, one of the present authors noticed a stimulated emission process of bosonic dark matter via the two-body decay of a mother particle in a thermal plasma similar to the ope…

Precise calculations for decays of Higgs bosons in extended Higgs sectors
Kodai Sakurai
We briefly introduce H-COUP_3.0, which we developed for evaluating higher-order corrections to any Higgs boson decays in various extended Higgs sectors. Focusing on two Higgs doubl…
