New Interpretation of the Recent Result of AMS-02 and Multi-component
Decaying Dark Matters with non-Abelian Discrete Flavor Symmetry    [PDF]

Yuji Kajiyama, Hiroshi Okada, Takashi Toma

We propose a new interpretation of the recent result of the AMS-02 experiment, that dark matter can be two component because it shows flash damp at around 125 GeV of the positron energy. By assuming two gauge-singlet fermionic decaying dark matters, we show that a model with non-Abelian discrete flavor symmetry, e.g. T_{13}, can successfully explain the damp of the positron fraction as well as the whole-range data. Few dimension six operators of universal leptonic decay of dark matters are allowed in our model, since its decay operators are constrained by the T_{13} symmetry. We also show that the lepton masses and mixings are consistent with current experimental data, due to the flavor symmetry.
