TITLE Interpretations of the DAMPE electron data
ABSTRACT The indirect detection of dark matter particles searches the signals produced by DM annihilation or decay which are all kinds of excesses in the energy spectrum of Cosmic Ray. The dark matter particle explorer(DAMPE) has already launched to space at December 27,2015. It has three advantages: large energy range, high energy revolution and strong background distinction. In this speech, I will talk about the structure of DAMPE, the advantage of DAMPE and the scientific goals of DAMPE. DAMPE published their new measurement of the total electrons plus positrons flux between 25 GeV and 4.6 TeV. A spectral softening at ∼ 0.9 TeV and a tentative peak at ∼ 1.4 TeV have been reported. In this talk, we will discuss the physical implications of the DAMPE data.
