T(13) Flavor Symmetry and Decaying Dark Matter
Yuji Kajiyama, Hiroshi Okada
We study a new flavor symmetric model with non-Abelian discrete symmetry T_{13}. The T_{13} group is isomorphic to Z_{13} \rtimes Z_3, and it is the minimal group having two comple…
Universally Leptophilic Dark Matter From Non-Abelian Discrete Symmetry
Naoyuki Haba, Yuji Kajiyama, Shigeki Matsumoto +2
The positron anomaly recently reported by the cosmic-ray measurements can be explained by the decaying dark matter scenario, where it decays mainly into leptons with the lifetime o…
Gauged B-L Leptogenesis
Yuji Kajiyama, Shaaban Khalil, Hiroshi Okada +1
We propose a new leptogenesis scenario in a gauged model with supersymmetry at the TeV energy scale. Instead of relying on the very small Yukawa couplings of the singlet neut…
