CascadeDecays.jl

CascadeDecays.jl provides topology-aware routing for sequential decays: it stores a flat binary cascade graph, resolves bracket-addressed propagators and vertices, and maps event-dependent masses and helicity angles into local amplitude building blocks.

Getting started

• Define a cascade with DecayTopology(...).
• Attach propagators and vertices with DecayChain(...).
• Build runtime kinematics with cascade_kinematics(...).
• Evaluate amplitudes with amplitude(...).

The main user-facing walkthrough is the tutorial page generated from the literate source in docs/integration_4body_b2ddKpi.jl.
