builder

import ampform_dpd.dynamics.builder

Dynamics builder functions for register_builder().

Note

As opposed to AmpForm, AmpForm-DPD defines dynamics over the entire decay chain, not a single isobar node. The dynamics classes and the corresponding builders would have to be extended to implement other dynamics lineshapes.

formulate_breit_wigner_with_form_factor(decay: ThreeBodyDecayChain) → tuple[Expr, dict[Symbol, complex | float]]

create_mass_symbol(particle: IsobarNode | Particle) → Symbol

get_mandelstam_s(decay: IsobarNode[Particle]) → Symbol
