Coulomb-Nuclear Interference: Theory and Practice for pp-Scattering at 13 TeV

Abstract

We provide a detailed reconsideration of the theoretical basis for the treatment of Coulomb-nuclear interference (CNI) and a corresponding thorough analysis of the procedure of extraction of the basic parameters ${\rho }^{pp},{\sigma }_{tot}^{pp}$ and $B^{pp}$ from the TOTEM data at $\sqrt{s}=13$ TeV. A more substantiated account of CNI, as well as an in-depth statistical analysis of the TOTEM data at low transferred momenta, give results that differ from those published by the TOTEM collaboration.
