A complex singlet extension of the Standard Model with a singlet fermion dark matter
Gi-Chol Cho, Chikako Idegawa, Rie Inumiya
We examine a complex singlet scalar extension of the Standard Model (CxSM) with an extra singlet fermion. Both the singlet scalar and fermion are dark matter (DM) candidates. It is…

Electron electric dipole moment and electroweak baryogenesis in a complex singlet extension of the Standard Model with degenerate scalars
Chikako Idegawa, Eibun Senaha
We study the possibility of electroweak baryogenesis in the standard model with a complex scalar field, focusing mainly on a degenerate scalar scenario. In our setup, CP violation…

Analyzing cancellation mechanism of the dark matter-quark scattering in a complex singlet extension of the Standard Model
Gi-Chol Cho, Chikako Idegawa
We investigate a suppression mechanism of dark matter and quark scattering amplitudes in a complex singlet extension of the Standard Model. It has been pointed out that, in a some…
