I just realized I don't know a simple thing. How do you experimentally verify, that photons are spin 1 particles? At least you cannot do it with the Stern-Gerlach experiment, because photons are not charged. The polarization effect is usually somewhat identified with the spin, but is it really the same? How do you calculate the theory of polarization measurements from the quantum mechanical principles? I've seen only classical explanations.
Suppose I throw a wild idea, that the electromagnetic potential is a 2nd-rank tensor [itex]A^{\mu\nu}[/itex], and four component potential has worked as an approximation of this, because they both give the Coulomb's force similarly, and the weak magnetic effects are the same (hopefully, I'm not 100% sure). What's the experimental results that contradict this?
