Dirac right-handed sneutrino dark matter and its signature in the gamma-ray lines
Ki-Young Choi, Osamu Seto
We show that a Dirac right-handed scalar neutrino can be weakly interacting massive particle in the neutrinophilic Higgs model. When the additional Higgs fields couple only to the…
Originally Asymmetric Dark Matter
Nobuchika Okada, Osamu Seto
We propose a scenario with a fermion dark matter, where the dark matter particle used to be the Dirac fermion, but it takes the form of the Majorana fermion at a late time. The rel…
Modulated reheating by curvaton
Ki-Young Choi, Osamu Seto
There might be a light scalar field during inflation which is not responsible for the accelerating inflationary expansion. Then, its quantum fluctuation is stretched during inflati…
Vector WIMP Miracle
Tomohiro Abe, Mitsuru Kakizaki, Shigeki Matsumoto +1
Weakly interacting massive particle (WIMP) is well known to be a good candidate for dark matter, and it is also predicted by many new physics models beyond the standard model at th…
