Observing Higgs boson production through its decay into gamma-rays: A messenger for Dark Matter candidates
Nicolas Bernal, Celine Boehm, Sergio Palomares-Ruiz +2
In this Letter, we study the gamma-ray signatures subsequent to the production of a Higgs boson in space by dark matter annihilations. We investigate the cases where the Higgs boso…
Light Dark Matter Candidate in B-L Gauged Radiative Inverse Seesaw
Yuji Kajiyama, Hiroshi Okada, Takashi Toma
We study a radiative inverse seesaw model with local B-L symmetry, in which we extend the neutrino mass structure that is generated through a kind of inverse seesaw framework to th…
Fermionic Dark Matter in Radiative Inverse Seesaw Model with U(1)_{B-L}
Hiroshi Okada, Takashi Toma
We construct a radiative inverse seesaw model with local B-L symmetry, and investigate the flavor structure of the lepton sector and the fermionic Dark Matter. Neutrino masses are…
Can A Higgs Portal Dark Matter be Compatible with the Anti-proton Cosmic-ray?
Hiroshi Okada, Takashi Toma
Recent direct detection experiments of Dark Matter (DM), CoGeNT and DAMA implicate a light DM of a few GeV. Such a light DM would generate a large amount of anti-proton since suppr…
Direct Detection of Leptophilic Dark Matter in a Model with Radiative Neutrino Masses
Daniel Schmidt, Thomas Schwetz, Takashi Toma
We consider an electro-weak scale model for Dark Matter (DM) and radiative neutrino mass generation. Despite the leptophilic nature of DM with no direct couplings to quarks and glu…
