“…Measurements of b-jet and c-jet spectra are compared to pp datapat s = 2.76 TeV and to PYTHIA predictions at both 2.76 and 5.02 TeV. We observea centrality-dependent suppression for b-jets in PbPb and a result that is consistentwith PYTHIA for both charm and bottom jets in pPb collisions.…”

“…The signal reweighting method is extended to use the next-to-leading order PowhegPythia8 Drell-Yan sample. We obtain promising results when comparing the signal reweighted Z′ sample to a fully simulated Pythia8 Z′ sample in Run 2 at √s = 13 TeV with 58.5 fb^{−1} of data. …”

“…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.…”

“…Our results are accurate to the next-to-leading order in QCD, and matched to parton showers through the MC@NLO method; thus, they are fully differential and based on unweighted events, which we shower by using both Herwig++ and Pythia8. We perform the computation in both the four-flavour and the five-flavour schemes, whose results we compare extensively at the level of exclusive observables. …”
