What's Changed
- Support for gamma-gamma collisions using the specific `EventKinematicsMassless` kinematics
- Python 3.12 Compatibility and binary wheels
- **SIBYLL***:
- The main Sibyll* model is available from `chromo.models.Sibyll23StarMixed` the other variants can be accessed from `chromo.extra_models.SibyllStarRho` (for example)
- **QGSJET** 01d, II-03 and II-04:
- More detailed information about interaction cross sections (total, diffractive, inelastic, etc.) for hadron-nucleon collisions
- For nuclei - projectiles heavier than proton - this is also possible at the cost of computational time by passing `full_AA = True` flag. Note that as in the case of DPMJet, these cross sections are calculated using "Glauber" MC and take some time to compute. The number of trials can be adjusted by setting `model.glauber_trials = 10000` or a reasonable number.
- By default, cross sections for nuclear targets (h-A and A-A) will be read out from precomputed tables, however only inelastic ones are available.
- For some current technical reasons, hadron-nucleus (h-A) cross sections are always taken from tables.
- Updated qgsjet tests, testing for cross section
- **DPMJET Update**:
- Updated to latest DPMJET III and PHOJET 19.3.7
- The models support again photon-nucleus, and photon-hadron, and photon-photon collisions. For non-nuclear targets the results between PHOJET and DPMJET should/are identical, Use PHOJET in this case, since it is easier to debug.
