Comparison of $\Sigma_{\mathrm{EEC}}$ section as a function of $R_{\mathrm{L}}$ with different values for StringPT:sigma using generated PYTHIA 8 events. The default setting is 0.335 (blue markers). The parton level distributions are made from parton jets that are matched to the charged jets with $p_{\mathrm{T}}$ range indicated in each figure.
