Small-scale structure from charged leptophilia

We consider a charged leptophilic extension of the Standard Model of particle physics as a minimal dark sector. It accomodates a WIMP paradigm at the TeV-scale that is sufficient to solve all small-scale problems of $\mathrm{\Lambda }$CDM and explain the excess of highly energetic cosmic ray Standard Model electrons and positrons presented recently by the DAMPE collaboration. The predictive power of this model allows to test it in the near future.
