Normalized $\Sigma_{\text{EEC}}$ as a function of $\langle p_{\mathrm{T}}^{\text{ch jet}} \rangle R_{\mathrm{L}}$ for $p_{\mathrm{T}}^{\text{ch jet}}$ in 20–40, 40–60, and 60–80 $\mathrm{GeV}/c$. Statistical and systematic uncertainties are combined in quadrature. The fit function is shown by the red curve, with the solid portion indicating the fitting range.
