Weak isospin Weak-isospin gauge fields

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Relation ID: weakisospin_to_weakfield
Relation type: Physical interaction / binding couples-interacts
Direction: source → target
Endpoint roles: source: Interacts with / binds; target: Interacts with / bound by
Authored annotation: weak-isospin coupling

Authored explanation

$SU(2)_L$ weak isospin couples to the weak gauge fields.

How to interpret this relation type

The source field, particle, charge, current, or interaction couples to, acts on, binds, forms, or stabilizes the target in the stated regime. The edge label and detail must identify the exact coupling, interaction, or binding claim and its qualifications.
