Goldstone and longitudinal polarization equivalence between off-shell $W$s
If I understand correctly, the couplings of the longitudinal component of the $W$ and $Z$ bosons should be "equivalent" to the Goldstone bosons they ate after SSB.
In practice, this makes ...

Why is the relation $M_W=M_Z\cos\theta_W$ true only at tree-level?
In Glashow-Weinberg-Salam electroweak theory, the relation $$M_W=M_Z\cos\theta_W\tag{1}$$ is said to be remain true only at the tree-level; it receives corrections from the loop diagrams. See here. ...

Could electroweak interactions derive from higgsing of gauged chiral symmetry?
A recent question discussed the practice of introducing electroweak interactions into chiral perturbation theory by gauging part of the chiral symmetry. Gauging chiral symmetry is normally regarded as ...
