Multiple Production of Photons in Quantum Electrodynamics
Abstract
A formalism intended to evaluate the expectation value of physical quantities directly has been applied to the processes involving multiple production of photons in quantum electrodynamics. This has been achieved by constructing the Green's function which is done by expanding it in terms of hard and soft photon parts of the electromagnetic field. A general treatment of infrared divergence is given. The cross section for $n$-photon production in Coulomb scattering and pair annihilation has been evaluated. The limitation of the expansion of the Green's function in terms of hard and soft photon parts is examined. A plausible generalization regarding the cross section of any primary process in quantum electrodynamics at high energies with $n$-photon emission in the final state is enunciated.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
