On ξ-process for DVCS-amplitude

arXiv:2011.04807 · doi:10.3390/sym12121996

Abstract

In this note, we demonstrate in detail the ξ-process implementation applied to the deeply virtual Compton scattering amplitude to ensure both the QCD and QED gauge invariance. The presented details are also important for understanding of the contour gauge used in different processes.
