Lessons from on inflation models: two-loop renormalization of in the scalar QED
Ayuki Kamada, Takumi Kuwahara
A non-minimal coupling has been attracting growing interest particularly in the context of inflation models, though its quantum nature is not clear yet. We study the renormaliz…
Lessons from on inflation models: two-scalar theory and Yukawa theory
Ayuki Kamada, Takumi Kuwahara
We demonstrate two properties of the trace of the energy-momentum tensor in the flat spacetime. One is the decoupling of heavy degrees of freedom; i.e., heavy degrees o…
Baryon-Dark Matter Coincidence in Mirrored Unification
Masahiro Ibe, Ayuki Kamada, Shin Kobayashi +2
About 80\% of the mass of the present Universe is made up of the unknown (dark matter), while the rest is made up of ordinary matter. It is a very intriguing question why the {\it…
Renormalization Effects on Electric Dipole Moments in Electroweakly Interacting Massive Particle Models
Takumi Kuwahara
The extended models of the standard model with a single Majorana fermion could be realized as the low-energy effective theory of the well-motivated ultraviolet models. We study the…
Renormalization Effects on Electric Dipole Moments in Electroweakly Interacting Massive Particle Models
Wataru Kuramoto, Takumi Kuwahara, Ryo Nagai
We study the renormalization effects on electric dipole moments in the models with new electroweakly interacting massive fermions. The electric dipole moments are generated by the…
