| 英文摘要 | Highly accurate measurements of cosmic ray electron flux by the dark matter particle explorer (DAMPE) ranging between 25 GeV and 4.6 TeV have recently been published. A sharp peak structure was found at 1.4 TeV. This unexpected peak structure can be reproduced by the annihilation/decay of a nearby dark matter (DM) halo. In this study, we adopt the decaying-DM model to interpret the 1.4 TeV peak. We found that the decay products of the local DM subhalo could contribute to the DMAPE peak with m (DM) = 3 TeV and tau 10(28) s. We also obtain constraints on DM lifetime and the distance of the local DM subhalo by comparison with DAMPE data. |
