Electric Dipole Moments of Charged Leptons with Sterile Fermions
Asmaa Abada, Takashi Toma
We address the impact of sterile fermions on charged lepton electric dipole moments. Any experimental signal of these observables calls for scenarios of physics beyond the Standard…
Nonthermal dark matter models and signals
Hiroshi Okada, Yuta Orikasa, Takashi Toma
Many experiments exploring weakly interacting massive particles (WIMPs) such as direct, indirect and collider searches have been carried out until now. However, a clear signal of a…
Non-thermal Production of Minimal Dark Matter via Right-handed Neutrino Decay
Mayumi Aoki, Takashi Toma, Avelino Vicente
Minimal Dark Matter (MDM) stands as one of the simplest dark matter scenarios. In MDM models, annihilation and co-annihilation processes among the members of the MDM multiplet are…
X-ray lines and self-interacting dark matter
Yann Mambrini, Takashi Toma
We study the correlation between a monochromatic signal from annihilating dark matter and its self-interacting cross section. We apply our argument to a complex scalar dark sector,…
Two Loop Neutrino Model with Dark Matter and Leptogenesis
Shoichi Kashiwase, Hiroshi Okada, Yuta Orikasa +1
We study a two-loop induced radiative neutrino model at TeV scale with global symmetry, in which we analyze dark matter and resonant leptogenesis. The model includes two kin…
A Model of Neutrino Mass and Dark Matter with an Accidental Symmetry
Amine Ahriche, Kristian L. McDonald, Salah Nasri +1
We present a model of radiative neutrino mass that automatically contains an accidental symmetry and thus provides a stable dark matter candidate. This allows a common framew…
