DiagramStyle

class DiagramStyle

Particle and momentum presentation for Feynman diagrams.

Examples

from symbolica.community import hepkit as hep
style = hep.DiagramStyle(show_momentum=True)
style.show_momentum
True

Attributes

Name	Description
debug	Show both vertex and edge indices unless individually overridden.
momentum_arrows	Draw momentum arrows beside particle lines.
show_edge_index	Show the physical edge indices.
show_momentum	Show momentum labels; None follows the render request.
show_node_index	Show the physical vertex indices.
show_particle	Show particle labels; None preserves the renderer default.
split_initial_state	Separate the incoming states of a cross-section drawing.

debug

DiagramStyle.debug: typing.Optional[builtins.bool]

Show both vertex and edge indices unless individually overridden.

Examples

hep.DiagramStyle(debug=True).debug
True

momentum_arrows

DiagramStyle.momentum_arrows: typing.Optional[builtins.bool]

Draw momentum arrows beside particle lines.

Examples

hep.DiagramStyle(momentum_arrows=True).momentum_arrows
True

show_edge_index

DiagramStyle.show_edge_index: typing.Optional[builtins.bool]

Show the physical edge indices.

Examples

hep.DiagramStyle(show_edge_index=True).show_edge_index
True

show_momentum

DiagramStyle.show_momentum: typing.Optional[builtins.bool]

show_particle

DiagramStyle.show_particle: typing.Optional[builtins.bool]

Show particle labels; None preserves the renderer default.

Examples

True

split_initial_state

DiagramStyle.split_initial_state: typing.Optional[builtins.bool]

Separate the incoming states of a cross-section drawing.

Examples
