Hadronization is a non-perturbative process, which theoretical description can not be deduced
from first principles. Modeling hadron formation, requires several assumptions and various
phenomenological approaches. Utilizing state-of-the-art Computer Vision and Deep Learning
algorithms, it is eventually possible to train neural networks to learn non-linear and non-
perturbative features of the physical processes.
Here, I would like to present the results of two ResNet networks, by investigating global and
kinematical quantities, indeed jet- and event-shape variables. The widely used Lund string
fragmentation model is applied as a baseline in √s=7 TeV proton-proton collisions to predict the
most relevant observables at further LHC energies. Non-liear QCD scaling properties were also
identified and validated by experimental data.
