Abstract
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 as μ→3e. We also discuss possible collider signatures of our model, both at the LHC and a future 100 TeV hadron collider. © 2018, Science China Press and Springer-Verlag GmbH Germany, part of Springer Nature
