The paper presents an updated set of parameters for the PYTHIA 8 event generator, focusing on reevaluating constraints from LEP and SLD on hadronization, particularly heavy-quark fragmentation and strangeness production. The authors combine updated fragmentation parameters with the new NNPDF2.3 LO PDF set for hadron collisions and use LHC data to constrain initial-state radiation and multi-parton interaction parameters. The updated parameters show significant improvements for both $ee$ and $pp$ collisions, though discrepancies remain for strange particles and baryons. The updated parameters are available as an option starting from PYTHIA 8.185, accessible by setting Tune:$ee = 7$ and Tune:$pp = 14$. The paper also discusses the tuning process, including the choice of strong coupling and PDF sets, and provides detailed comparisons with experimental data to illustrate the improvements and remaining discrepancies.The paper presents an updated set of parameters for the PYTHIA 8 event generator, focusing on reevaluating constraints from LEP and SLD on hadronization, particularly heavy-quark fragmentation and strangeness production.
