Evading Direct Dark Matter Detection in Higgs Portal Models
Giorgio Arcadi, Christian Gross, Oleg Lebedev +2
Many models of Higgs portal Dark Matter (DM) find themselves under pressure from increasingly tight direct detection constraints. In the framework of gauge field DM, we study how s…
Multicomponent Dark Matter from Gauge Symmetry
Giorgio Arcadi, Christian Gross, Oleg Lebedev +3
The composition of Dark Matter (DM) remains an important open question. The current data do not distinguish between single- and multi-component DM, while in theory constructions it…
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. We show that in order to have a non-vanishing contribution to electric dipole moments, the mini…
Implications of Two-component Dark Matter Induced by Forbidden Channels and Thermal Freeze-out
Mayumi Aoki, Takashi Toma
We consider a model of two-component dark matter based on a hidden symmetry, in which relic densities of the dark matter are determined by forbidden channels and thermal f…
Electron electric dipole moment in Inverse Seesaw models
Asmaa Abada, Takashi Toma
We consider the contribution of sterile neutrinos to the electric dipole moment of charged leptons in the most minimal realisation of the Inverse Seesaw mechanism, in which the Sta…
Systematic U(1)_{B-L} Extensions of Loop-Induced Neutrino Mass Models with Dark Matter
Shu-Yu Ho, Takashi Toma, Koji Tsumura
We study the gauged U(1)_{B-L} extensions of the models for neutrino masses and dark matter. In this class of models, tiny neutrino masses are radiatively induced through the loop…
