Three-point Green function of massless QED in position space to lowest order
arXiv:0808.2448 · doi:10.1088/1751-8113/42/3/035404
Abstract
The transverse part of the three-point Green function of massless QED is determined to the lowest order in position space. Taken together with the evaluation of the longitudinal part in arXiv:0803.2630, this gives a relation for QED which is analogous to the star-triangle relation. We relate our result to conformal-invariant three-point functions.
