%0 Journal Article %T Probing the mathematical nature of the photon field %A Walter Smilga %J Physics %D 2009 %I arXiv %X The mathematical content of the interaction term of quantum electrodynamics is examined under the following assumption: It is presumed that the apparent degrees-of-freedom of the photon field reflect the kinematical degrees-of-freedom of the two-particle state space of massive fermions, rather than independent degrees-of-freedom of the photon field. This assumption is verified by reproducing the numerical value of the fine-structure constant. %U http://arxiv.org/abs/0901.4917v5
