Why is the Higgs field a scalar field?

  1. May 8, 2013 #1
    as i understand it the higgs field is a spin-0 scalar field that gives mass to elementry particles. How is it a scalar field? I thought it was homogenous.

    Is it possible you're confusing the Higgs field with the Higgs boson? The Higgs field is a uniform background scalar field whose existence permits other particles to have mass in an electroweak gauge invariant manner. The Higgs boson is an excitation of the Higgs field. Since the Higgs field is a scalar field, the Higgs boson has spin 0.

    It IS a scalar [spin 0] field....

    Wikipedia has a pretty good general description here:



    Like other components of the Standard Model, Higg's fields are manual insertions [mathematical additions] individually tailored with the specific properties needed to provide different particles with observed mass; We need a mechanism of spontaneous symmetry breaking to bring forth mass; The Higgs Field provides such a tool. Symmetry transformations are generated on Hilbert space of states by unitary operators.

    When you know the additional physical characteristics required in a partial theory, you can invent mathematics to produce them and glue them into whatever model you'd like. Like adding the Higg's field in early cosmology to provide spontaneous symmetry breaking.

    I think it is the requirement of symmetry-breaking.
