Photon's spin

  1. Dec 9, 2013 #1
    Sorry if it is a silly question: Photons have spin-1 and therefore they have theoretically three possible spin states (1,0,-1), For the ±1 case I can see the relation to the ±helicity, but what corresponds physically to the 0 state case?

    The spin-0 case can be eliminated through a choice of gauge. So it's not considered physical.
