A radiative neutrino mass model with semi-annihilating boosted dark matter
Motoko Fujiwara, Takashi Toma
Boosted dark matter can provide a distinctive signature of a non-minimal dark sector. In this work, we construct a radiative neutrino mass model that allows for the production of b…
Two component pseudo-Nambu-Goldstone-boson dark matter
Riasat Sheikh, Takashi Toma, Koji Tsumura
We study a two-component pseudo-Nambu-Goldstone-boson (pNGB) dark matter (DM) model motivated by boosted dark matter (BDM). The model is based on a complex scalar field charged und…
Phenomenology of scotogenic-like 3-loop neutrino mass models
Asmaa Abada, Nicolás Bernal, Antonio E. Cárcamo Hernández +3
In this talk, we discuss the phenomenology of radiative 3-loop seesaw models. The 3-loop suppression allows the new particles to have masses at the TeV scale, along with relatively…
Pheno & Cosmo Implications of Scotogenic 3-loop Neutrino Mass Models
Asmaa Abada, Nicolás Bernal, Antonio E. Cárcamo Hernández +3
Radiative seesaw models are examples of interesting and testable extensions of the Standard Model to explain the light neutrino masses. In radiative models at 1-loop level, such as…
Electric dipole moments of charged leptons in models with pseudo-Dirac sterile fermions
Asmaa Abada, Takashi Toma
In this work, we address the impact of a small lepton number violation on charged lepton electric dipole moments - EDMs. Low-scale seesaw models protected by lepton number symmetry…
