摘要

We study the recent e± cosmic ray excess reported by DAMPE in a Hidden Valley Model with lepton-portal dark matter.We find the electron-portal can account for the excess well and satisfy the DM relic density and direct detection bounds,while electron+muon/electron+muon+tau-portal suffers from strong constraints from lepton flavor violating observables,such asμ →3e.We also discuss possible collider signatures of our model,both at the LHC and a future 100 TeV hadron collider.
