Detailed Description

Mapper and dynamic identifiers for decay channels.

The decay layer mirrors the observable layer:

• Decays is the historical static enum for builtin decay channels;
• DecayId is the string-based dynamic identifier used for both builtin and custom decays.

Static relations (Decays -> Observables) are still read from decay_observable_mapping(). Runtime relations (DecayId -> ObservableId) are stored in DecayGraph.

Typedef Documentation

DecayId

using DecayId = IdOf<DecayTag>

Strongly typed dynamic identifier for decays.

Definition at line 39 of file decay_ids.hpp.

Function Documentation

decay_external_mapping()

const std::map< Decays, LhaID > & decay_external_mapping ( )

inline

Placeholder external mapping for decays.

Decays currently have no builtin FLHA-like external identifier. The empty map keeps DecayMapper compatible with GenericMapperWithExt, so a real external mapping can be added later without changing the public mapper shape.

Returns

Empty static map.
