AMS02 positron excess from decaying fermion DM with local dark gauge symmetry
Positron excess observed by PAMELA, Fermi and AMS02 may be due to dark matter (DM) pair annihilation or decay dominantly into muons. In this paper, we consider a scenario with thermal fermionic DM (χ) with mass ∼O(1–2) TeV decaying into a dark Higgs (ϕ) and an active neutrino (νa) instead of the SM...
