PYTHIA8 predictions to the Underlying event measurements using different PDF sets
January 14, 2023
In this study, we use PYTHIA 8.3 for the simulation of multiparton interactions using different sets of parton distribution functions (PDF). Altogether four parameters were selected for the final tune depending on their sensitivity to the selected observables at 7 TeV published by ATLAS Collaboration. Simulated experimental analysis data are obtained using the Rivet analysis toolkit. These tunes describe the selected data reasonably well. These tuning results are also compared with the other popular choice, i.e. Monash tune.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
