Testing of KNO-scaling of charged hadron multiplicities within a Machine Learning based approach

Abstract

The results of a Machine Learning-based method is presented here to investigate the scaling properties of the final state charged hadron and mean jet multiplicity distributions. Deep residual neural network architectures with different complexities are utilized to predict the final state multiplicity distribution from the parton-level final state, generated by the Pythia Monte Carlo event generator. Hadronization networks were trained by √s = 7 TeV events, while predictions have been made for various LHC energies from √s = 0.9 TeV to 13 TeV. Scaling properties were adopted by the networks at hadronic level, indeed KNO-scaling is preserved—although, the scaling of the mean jet multiplicity distributions varies for the applied models.
