Webwhich particular Green’s function happens to be the Feynman propagator. The Feynman propagator is aGreen’s function A free scalar field obeys the Klein–Gordon equation (∂2 + m2)Φ(ˆ x) = 0. Consequently, the Feynman propagator (1) for the Φ is a Green’s function of that equation,ˆ (∂2 +m2)GF(x −y) = −iδ(4)(x− y). (5) Web(Eq.24') Photon's propagator includes unreal zero-component scalar polarized photon (= g00= - 1 ) with negative probability. Propagators of (virtual) photon field is very similar to Klein-Gordon scalar field's propagator ( this p.7-8, this p.46 ). There are two different points between Klein-Gordon and photon's propagators. how far back can you claim pip
