Decay¶

class madspace.Decay¶

Bases: pybind11_object

One node of the s-channel decay tree built by Topology.

property child_indices¶: Indices of the child nodes.

property e_max¶: Upper bound on the node energy.

property e_min¶: Lower bound on the node energy.

property index¶: Index of this node in the decay list.

property mass¶: Propagator mass of this node.

property on_shell¶: Whether this node’s invariant is fixed to mass (a resonance).

property on_shell_boundary¶: Whether the on-shell condition sits on the integration boundary.

property parent_index¶: Index of the parent node.

property pdg_id¶: PDG id of the propagator.

property width¶: Propagator width of this node.
