Coulomb-nuclear interference effects in proton-proton scattering: A simple new eikonal approach: https://arxiv.org/abs/2007.07827
Loyal Durand, Phuoc Ha
We present a simple new approach to the treatment of Coulomb-nuclear interference and form-factor effects in high-energy proton-proton scattering in the context of eikonal models for the scattering amplitude. We show that the corrections to the nuclear and Coulomb amplitudes do not depend sensitively on the details of the eikonal amplitude and can be taken as universal, and present parametrizations for the necessary corrections. We also present a simple model for the nuclear scattering amplitude useful for data analysis at small momentum transfer which builds in the proper nuclear phase and the diffraction zeros in the real and imaginary parts of the amplitude.

This is a brief analysis of the basic formula from arXiv:2007.07827. Some inconsistency has been identified.
