Summary

The complex scalar field transforming as an SU(2)LSU(2)_L doublet with weak hypercharge Y=1/2Y=1/2 in the Standard Model. Its nonzero vacuum expectation value breaks electroweak symmetry.

Higgs doublet fieldHiggs field

Permalink to relation

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

Authored explanation

After expansion about the electroweak vacuum and gauge fixing, three doublet degrees of freedom supply longitudinal W±W^\pm and ZZ modes and one physical scalar field remains.

How to interpret this relation type

The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

Higgs doublet fieldHiggs–gauge interaction

Permalink to relation

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

Authored explanation

The Higgs kinetic term couples the doublet to SU(2)LSU(2)_L and U(1)YU(1)_Y 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.

Permalink to relation

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

Authored explanation

The Higgs doublet and its vacuum configuration supply the scalar degrees of freedom used by the electroweak Higgs mechanism.

How to interpret this relation type

The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.
