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…
Constraints on the Sommerfeld-enhanced dark matter annihilation from the gamma rays of subhalos and dwarf galaxies
Bo-Qiang Lu, Yue-Liang Wu, Wei-Hong Zhang +1
The substructures of the Galactic dark matter halo such as dark matter subhalos and dwarf galaxies have very low velocity dispersions, which makes them useful in constraining the s…
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…
