Поправки КЭД к упругому рассеянию электрона на ядре с большой передачей импульса

On the QED corrections to elastic electron scattering at high momentum transfer: https://arxiv.org/abs/2102.08069
D.H.Jakubassa-Amundsen
Estimates of QED and dispersion effects on the cross section for elastic electron scattering from a 12C nucleus are provided for collision energies in the range of 120-450 MeV. While in general such corrections are smoothly varying with energy or scattering angle, they show structures in the vicinity of diffraction minima which are very sensitive to details of the theoretical models. This casts doubt on the assertion that the discrepancy between QED background-corrected experimental data and theory in these minima originates solely from dispersion.
