In general: yes. But i am feeling, that the unitary gauge must be exact without neglections. The context: http://ajbell.web.cern.ch/ajbell/Documents/eBooks/Quarks & Leptons.pdf, eq. 14.56, page 327

Thank you very much for your reply. I am glad that this point is now clear for me: it is only an approximation! But what about the physics of this approximation? Does it mean, that the unitary gauge ist an approximation also ? And that the Goldstone-particles does vanish from the lagrangian not...

Dear @ll, the central point (for the unitary gauge) in the higgs-mechanism is the equality Φ = (v + η + iξ) = (v + η)ei(ξ/v) (see for example Halzen, Martin: Quarks and Leptons, eq. 14.56) Φ = complex scalar Field v = vacuum that breaks the symmetry spontaneously η,ξ = shifted...
