Similarly, the lack of an edge in the e + + e − spectrum implies that DM that dominantly annihilates or decays into 2e is now firmly excluded, and one can constrain the BR of the subdominant e ± primary channel. Assuming that DM annihilates into leptons with lepton flavor components BR e , BR µ , BR τ that sum to unity, BR e + BR µ + BR τ = 1 one can constrain the allowed regions in light of the PAMELA, FERMI and HESS **data** together with the other constraints. To clarify the situation we show the constraints on the branching fractions for three distinct cases:
