Best fit for the branching fractions for each DM mass m_χ assuming only annihilations into lepton and pairs. The red line indicates on the right vertical axis the best value. As the DM mass exceeds the energy of the last data point, the fit improves discontinuously and the drops sharply, hence the kink in the red curve above 400 GeV. Between 20 and 30 TeV, the three lepton channels yield similar spectra in the range of positron energies that come into play in the fit. The branching ratio into τ⁺τ⁻ should be understood as a sum over the three lepton families.
