comment How does charge work if photons are neutral?
I'm seeing no answer here. One candidate assumes one electron intrinsically knows the others charge; I believe the photon is required to convey that fact. Another resorts to the variation in particle mass, which of course is irrelevant, since it would not help us with the electron-positron interaction. We need to show how the electromagnetic field, embodied in the photon or photons, relates the charges and conveys this to its two client particles. Does it depend on the polarization of the photon, its phase, or what? In short I also would love to know the answer to this.
