Origins of sharp cosmic-ray electron structures and the DAMPE excess
Xian-Jun Huang, Yue-Liang Wu, Wei-Hong Zhang +1
Nearby sources may contribute to cosmic-ray electron (CRE) structures at high energies. Recently, the first DAMPE results on the CRE flux hinted at a narrow excess at energy ~1.4 T…
Antiprotons from dark matter annihilation through light mediators and a possible excess in AMS-02 data
Xian-Jun Huang, Chun-Cheng Wei, Yue-Liang Wu +2
We show that in the scenario where dark matter (DM) particles annihilate through light mediators, the energy spectra of the final state cosmic-ray particles depend strongly on the…
Connecting the LHC diphoton excess to the Galatic center gamma-ray excess
Xian-Jun Huang, Wei-Hong Zhang, Yu-Feng Zhou
The recent LHC Run-2 data have shown a possible excess in diphoton events, suggesting the existence of a new resonance with mass ~GeV. If plays the role of a por…
A 750 GeV dark matter messenger at the Galactic Center
Xian-Jun Huang, Wei-Hong Zhang, Yu-Feng Zhou
The first data from the LHC Run-2 have shown a possible excess in diphoton events with invariant mass GeV, suggesting the existence of a new resonance which may decay do…
