AmpForm-DPD 0.4.2

See all documentation for this version here.

✨ New features

• Load a complete serialized model through load_workspace() and Workspace (#221)
• Formulate the published $\Lambda_b$ and COMPASS models straight from their serialized definitions (#220)
• Convert serialized coordinates into a symbolic map with formulate_kinematic_map() (#223)
• Compile workspace functions and distributions to numpy or jax with compile_workspace() (#224)
• Verify serialized reference values with validate_checksums() (#225)

⚠️ Enhancements and optimizations

• Narrow node types with TypeIs in is_isobar(), so branches type-check correctly (#220)

⚠️ API changes

• Vertex is now a tagged union of HelicityVertex, ParityVertex and LSVertex instead of a base class (#220)

⚠️ Changes that may affect behavior

• Multichannel Breit-Wigner uses complex phase space and LS-derived coupling names (#220)

🐛 Bug fixes

• Cache tests no longer assert platform-dependent hash digests (#221)
• Child spins are read from final-state definitions when a chain has integer nodes (#220)
• Third-party GitHub Actions are pinned to immutable commit SHAs (#224)
• A failing checksum target no longer aborts validation of the remaining ones (#225)

📝 Documentation

• Validate the notebook intensity checksum through formulate_kinematic_map() (#223)
• Render decay topologies with Mermaid and tidy the notebook output in Sphinx (#226)

🔨 Maintenance

• Update uv.lock for the pytest-describe test dependency (#227)
• Require qrules>=0.10.12 instead of the qrules[viz] extra (#226)

🖱️ Developer Experience

• Group tests into describe_* blocks with pytest-describe (#227)
• Drop Graphviz as a system dependency for building the documentation (#226)
