Minimal Majoron Dark Matter from a Discrete Gauge Symmetry
Subaru Fujisawa, Qiuyue Liang, Shigeki Matsumoto +2
We investigate majoron dark matter in a minimal setup, where the Standard Model is extended by three right-handed neutrinos and a complex scalar field. The theory is defined by an…

Detecting Sterile Neutrino Dark Matter at MeV Gamma-Ray Observatories
Subaru Fujisawa, Tatsuya Hayashi, Shigeki Matsumoto +1
We explore the indirect detection of sterile neutrino dark matter within the gauged extension of the Standard Model, in which three right-handed neutrinos account for…
