1. An extension of the SM based on effective Peccei–Quinn Symmetry / Suematsu, Daijiro
Peccei–Quinn (PQ) mechanism based on a chiral global U (1) symmetry is considered to be a simple and elegant solution for strong CP problem. [...]

2. Dark matter stability and one-loop neutrino mass generation based on Peccei–Quinn symmetry / Suematsu, Daijiro
We propose a model which is a simple extension of the KSVZ invisible axion model with an inert doublet scalar. [...]

4. Leptogenesis in a neutrino mass model coupled with inflaton / Suematsu, Daijiro
We propose a scenario for the generation of baryon number asymmetry based on the inflaton decay in a radiative neutrino mass model extended with singlet scalars. [...]

7. Lepton number asymmetry via inflaton decay in a modified radiative seesaw model / Kashiwase, Shoichi ; Suematsu, Daijiro
We propose a non-thermal scenario for the generation of baryon number asymmetry in a radiative neutrino mass model which is modified to realize inflation at the early Universe. [...]
