Quantum Number Conservation Rules


















QRules is a Python package for validating and generating particle reactions using
quantum number conservation rules. The user only has to provide a certain set of
boundary conditions (initial and final state, allowed interaction types, expected decay
topologies, etc.). QRules will then span the space of allowed quantum numbers over all
allowed decay topologies and particle instances that correspond with the sets of allowed
quantum numbers it has found.
The resulting state transition objects are particularly useful for amplitude analysis
/ Partial Wave Analysis as they contain all information (such as expected masses,
widths, and spin projections) that is needed to formulate an amplitude model.
