Interpretation of the cosmic ray positron and electron excesses with an annihilating-decaying dark matter scenario
Lei Feng, Zhaofeng Kang, Qiang Yuan +2
The precise measurements of energy spectra of cosmic ray positrons and/or electrons by recent experiments show clear excesses above 10 GeV. Moreover, a potential sharp spectral fea…
Confronting the DAMPE Excess with the Scotogenic Type-II Seesaw Model
Ran Ding, Zhi-Long Han, Lei Feng +1
The DArk Matter Particle Explorer (DAMPE) has observed a tentative peak at $E\sim1.4~\TeV$ in the cosmic-ray electron spectrum. In this paper, we interpret this excess in the scoto…
Interpretations of the possible 42.7 GeV -ray line
Lei Feng, Yun-Feng Liang, Tie-Kuang Dong +1
Recently Liang et al. found a tentative line signal at about 43 GeV in the directions of sixteen nearby Galaxy Clusters. If arising from dark matter annihilation, the mass of the d…
Closing in on singlet scalar dark matter: LUX, invisible Higgs decays and gamma-ray lines
Lei Feng, Stefano Profumo, Lorenzo Ubaldi
We study the implications of the Higgs discovery and of recent results from dark matter searches on real singlet scalar dark matter. The phenomenology of the model is defined by on…
Decaying Asymmetric Dark Matter Relaxes the AMS-Fermi Tension
Lei Feng, Zhaofeng Kang
The first result of AMS-02 confirms the positron fraction excess observed by PAMELA, but the spectrum is somewhat softer than that of PAMELA. In the dark matter (DM) interpretation…
