http://conferences.fnal.gov/g4tutorial/g4cd/Slides/IEEE/hadronicPhys.pdf QED is based on the assumption that complex interactions of many electrons and photons can be represented by fitting together a suitable collection of the above three building blocks and then using the probability amplitudes to calculate the probability of any such complex interaction. See more In particle physics, quantum electrodynamics (QED) is the relativistic quantum field theory of electrodynamics. In essence, it describes how light and matter interact and is the first theory where full agreement between See more QED action Mathematically, QED is an abelian gauge theory with the symmetry group U(1), defined on See more An argument by Freeman Dyson shows that the radius of convergence of the perturbation series in QED is zero. The basic argument … See more The first formulation of a quantum theory describing radiation and matter interaction is attributed to British scientist Paul Dirac, who (during the … See more Introduction Near the end of his life, Richard Feynman gave a series of lectures on QED intended for the lay public.
