gammaloop Class

IntegrandGraphGroup()

Graphs and shared orientation, loop-basis, threshold, and cut data in one group.

Member details

group_id

Property · read-only
#
group_id: int

Zero-based graph-group identifier within the integrand.

graphs

Property · read-only
#
graphs: list[IntegrandGraph]

Graphs in this group, with the representative graph marked as master.

orientation_edge_ids

Property · read-only
#
orientation_edge_ids: list[int]

Edge identifiers that establish the ordering of every orientation signature.

orientations

Property · read-only
#
orientations: list[IntegrandOrientation]

Available causal-flow orientations for the representative graph.

loop_momentum_bases

Property · read-only
#
loop_momentum_bases: list[IntegrandLoopMomentumBasis]

Available loop-momentum bases for the representative graph.

threshold_esurface_ids

Property · read-only
#
threshold_esurface_ids: list[int]

Ordered identifiers of threshold E-surfaces retained for the group.

threshold_esurfaces

Property · read-only
#
threshold_esurfaces: list[IntegrandThresholdEsurface]

Structured metadata for the retained threshold E-surfaces.

cuts

Property · read-only
#
cuts: list[IntegrandCut]

Cross-section cuts; empty for amplitude graph groups.
