High-Energy Scattering vs Static QCD Strings

TL;DR

This paper compares the shape of the interaction region in high-energy proton scattering with static QCD strings, revealing similarities at certain energies and proposing a modified string width-length relationship at very large lengths.

Contribution

It introduces a novel comparison between high-energy scattering regions and static QCD strings, and suggests a modified string width-length relationship at large scales.

Findings

Similarity between scattering interaction region and static QCD string at certain energies

Disappearance of this similarity at LHC energies with many-Pomeron exchanges

Proposal of a modified relationship between string width and length at large scales

Abstract

We discuss the shape of the interaction region of the elastically scattered protons stipulated by the high-energy Pomeron exchange which turns out to be very similar with the shape of the static string representing the confining QCD flux tube. This similarity disappears when we enter the LHC energy region, which corresponds to many-Pomeron exchanges. Reversing the argument we conjecture a modified relationship between the width and the length of the confining string at very large lengths.
