Dirac equation for electron in EM and Higgs fields?

  1. Dec 21, 2011 #1
    Is this the correct form for a Dirac electron in a Higgs field with scalar potential [itex]\phi[/itex] and an electromagnetic field with vector potential [itex]A_\mu[/itex]

    [itex]i \gamma^\mu \partial_\mu \psi = g \phi \psi + e \gamma_\mu A^\mu \psi [/itex]

    where [itex]g[/itex] is the coupling constant to the Higgs field and [itex]e[/itex] is the coupling constant to the electromagnetic field?

    Looks Ok to me. And φ = v + h.

    Thanks a lot.

    I guess v is the Higgs vacuum expectation value and h is the physical Higgs field.
