Probing pseudo-Goldstone dark matter at the LHC
Katri Huitu, Niko Koivunen, Oleg Lebedev +2
Pseudo-Goldstone dark matter coupled to the Standard Model via the Higgs portal offers an attractive framework for phenomenologically viable pseudo-scalar dark matter. It enjoys na…
Probing pseudo Nambu-Goldstone boson dark matter at loop level
Koji Ishiwata, Takashi Toma
In the standard model extended by a single complex scalar boson with a softly broken global U(1) symmetry, a pseudo Nambu-Goldstone boson becomes a candidate for dark matter. In th…
Boosted Self-interacting Dark Matter in a Multi-component Dark Matter Model
Mayumi Aoki, Takashi Toma
In models of multi-component dark matter, the lighter component of dark matter can be boosted by annihilations of the heavier state if mass splitting is large enough. Such relativi…
Neutrino masses from Planck-scale lepton number breaking
Alejandro Ibarra, Patrick Strobl, Takashi Toma
We consider an extension of the Standard Model by right-handed neutrinos and we argue that, under plausible assumptions, a neutrino mass of is naturally g…
A new mechanism of sterile neutrino dark matter production
Johannes Herms, Alejandro Ibarra, Takashi Toma
We consider a scenario where the dark matter candidate is a sterile neutrino with sizable self-interactions, described by a dimension-six operator, and with negligible interactions…
Electric Dipole Moments in the Minimal Scotogenic Model
Asmaa Abada, Takashi Toma
In this work we consider a minimal version of the scotogenic model capable of accounting for an electron electric dipole moment within experimental sensitivity reach in addition to…
