Does anyone know where I can find:

  • gauge boson propagators (in an unfixed gauge) for the unphysical Electroweak gauge bosons $A^1_\mu$, $A^2_\mu$, $A^3_\mu$ and $A^4_\mu$ whose combinations give the physical $W^+_\mu$, $W^-_\mu$, $A_\mu$ and $Z_\mu$? (With the form of the Higgs doublet clearly stated).
  • vertex couplings for $A^1_\mu$, $A^2_\mu$, $A^3_\mu$ and $A^4_\mu$ with the Higgs
  • propagator for the Higgs boson field
  • propagator of the Golstone boson arising from the Higgs mechanism in EW
  • couplings of the Goldstone boson to the fields

I want to compute radiative corrections to some of the propagators of $A^1_\mu$, $A^2_\mu$, $A^3_\mu$ and $A^4_\mu$ due to the higgs boson, but I would like to do that (analytically) without deriving all feynman rules by myself.

  • $\begingroup$ The propagators for all vector bosons look pretty much the sense, and those of the scalar bosons also all look the same, it doesn't matter where these bosons come from. I don't understand the question. $\endgroup$

  • $\begingroup$ Could you tell me where I can find them? No doubt they may look similar, I just don't know them and don't know where to find them, specially for the unphysical fields. $\endgroup$

For anyone interested, I found a good document with all Feynman rules and different notations:
