Packages
| Package | Description | Latest version |
|---|---|---|
| ASCIIEventTree | PYTHIA 8 plugin that renders the event record as an ASCII decay tree after each fully-generated event, with options to suppress parton-shower copies, deduplicate shared particles, and annotate multi-body production vertices. | v8318.00 |
| BcVegPy | Interface to the BCVEGPY Fortran generator for the hadronic production of $B_c$ mesons, providing S-wave, P-wave, color-octet, and 2S $B_c$ states to Pythia as a Les Houches Accord user process (`LHAup`). | HEAD |
| DipoleCascade | PYTHIA 8 plugin implementing Mueller dipole evolution in transverse impact-parameter space, generating proton, pion, and virtual-photon dipole states and computing total, elastic, and diffractive Good-Walker cross sections. | HEAD |
| ExampleML | This is an ML example package which accesses an ONNX model and uses the ORT library to perform inference using this model. | v8318.00 |
| GenXicc | Interface to the GENXICC Fortran generator for the hadronic production of the doubly heavy baryons $\Xi_{cc}$, $\Xi_{bc}$, and $\Xi_{bb}$, and the corresponding $\Omega$ baryons, providing these to Pythia as a Les Houches Accord user process (`LHAup`). | HEAD |
| Hdsense | Computes the hadronization sensitivity of an observable in terms of the induced Fisher Information matrix over the hadronization parameters. | v8318.01 |
| IRCExplorer | Computes and stores observables at different scales in the evolution of a Pythia event, enabling studies of a shower's IRC-safety via the entropy gradient with respect to the evolution scale, as well as hadronization-sensitivity studies via the induced Fisher Information matrix. | v8318.00 |
| SherpaFrag | Interfaces Pythia 8's colour-singlet systems to Sherpa's cluster hadronization model, passing them to Sherpa instead of the Lund fragmentation model. | v8318.00 |
| SherpaShower | Interfaces Pythia 8's shower framework to Sherpa, providing a ShowerModel with paired space-like and time-like showers driven by Sherpa's own parton-shower machinery. | v8318.00 |
| SimpleCluster | Alternate hadronization model based on cluster fragmentation, where gluons are split into quark-antiquark pairs at the end of the parton shower and color-neutral clusters undergo two-body decays to hadrons. | v8318.00 |
