Dark Matter Annihilation from Nearby Ultra-compact Micro Halos to Explain the Tentative Excess at ~1.4 TeV in DAMPE data

Fengwei Yang, Meng Su, Yue Zhao

The tentative 1.4 TeV excess in the $e^{+}{e}^{-}$ spectrum measured by The DArk Matter Particle Explorer (DAMPE) motivates the possible existence of one or more local dark matter concen…
