Revisiting Multi-Component Dark Matter with New AMS-02 Data
Chao-Qiang Geng, Da Huang, Chang Lai
We revisit the multi-component leptonically decaying dark matter (DM) scenario to explain the possible electron/positron excesses with the recently updated AMS-02 data. We find tha…
Loop-induced Neutrino Masses: A Case Study
Chao-Qiang Geng, Da Huang, Lu-Hsing Tsai
We study the cocktail model in which the Majorana neutrino masses are generated by the so-called "cocktail" three-loop diagrams with the dark matter particle running in the loops.…
Correlation Between Muon and
Wei-Chi Chiu, Chao-Qiang Geng, Da Huang
While the muon anomaly can be successfully explained by some new physics models, most of them are severely constrained by the bound. This tension is more transpare…
X-ray Line from the Dark Transition Electric Dipole
Chao-Qiang Geng, Da Huang, Lu-Hsing Tsai
We study a two-component dark matter (DM) model in which the two Majorana fermionic DM components with nearly degenerate masses are stabilized by an symmetry and interact wit…
Cosmic Ray Excesses from Multi-component Dark Matter Decays
Chao-Qiang Geng, Da Huang, Lu-Hsing Tsai
We use multi-component decaying dark matter (DM) scenario to explain the possible cosmic ray excesses in the positron fraction recently confirmed by AMS-02 and the total …
