Upper bounds at 95% confidence on the DM annihilation cross-section ⟨σ_annv⟩ for $b\overline{b},{\mu }^{-}{\mu }^{+}$, and τ⁻τ⁺ states making use of six redshift bins and ten energy bins. The unresolved blazar contribution to the UGRB is included as the astrophysical background component in the analysis. For reference, dashed lines indicate the limits obtained without subtracting the blazar contribution. The thermal relic cross-section for WIMPs (Steigman et al. 2012) is shown as dashed-dot lines. The upper bounds are presented for three DM clumping scenarios: LOW (green), MID (orange) and HIGH (purple).
