Long-range potential and the fine structure of the diffraction peak

TL;DR

This paper investigates how string-like quark potentials at large distances can cause oscillations in the differential elastic cross section of hadron scattering at small momentum transfer, using experimental data to determine potential parameters.

Contribution

It demonstrates that string-like quark potentials can produce observable oscillations in scattering cross sections and extracts potential parameters from experimental data.

Findings

String-like quark potentials induce oscillations in the differential cross section.

Experimental data at small |t| supports the presence of these oscillations.

Parameters of the potential are quantitatively determined.

Abstract

The possibility of oscillations in the differential elastic cross section of hadron scattering at small momentum transfer is studied. It is shown that string-like quark potentials at large distances can lead to such small oscillations, and an analysis of the experimental data at small $|t|$ allows the determination of the parameters of the potential.
