Leptophilic dark matter in gauged $$U(1)_{L{_e}-L_{\mu }}$$ U(1)Le-Lμ model in light of DAMPE cosmic ray $${e{^+}} + {e{^-}}$$ e++e- excess
Abstract Motivated by the very recent cosmic-ray electron+positron excess observed by DAMPE collaboration, we investigate a Dirac fermion dark matter (DM) in the gauged $${{L_e} - {L_\mu }}$$ Le-Lμ model. DM interacts with the electron and muon via the $$U(1)_{e-\mu }$$ U(1)e-μ gauge boson $$Z^\prim...
