“…The results from data are unfolded to particle level and compared to calculations of the matrix element from Monte Carlo generators Alpgen+Pythia and Sherpa interfaced to a parton shower. The results show that Sherpa tends to model Z/γ$^{∗}$+jets production in high-$_{pT}$ regions of phase space much better than Alpgen+Pythia.…”
