Relevance of ultra-soft gluons and kt resummation for total cross-sections

TL;DR

This paper demonstrates that including ultra-soft gluons and their transverse momentum resummation moderates the rapid increase of mini jet cross sections, leading to more realistic predictions of total cross-sections.

Contribution

It introduces a method to incorporate ultra-soft gluons and k_t resummation to improve total cross-section calculations in high-energy physics.

Findings

Ultra-soft gluons suppress the rise of mini jet cross sections.

k_t resummation yields more realistic total cross-section estimates.

The approach aligns theoretical predictions with experimental data.

Abstract

Inclusion of down to zero-momentum gluons and their k_t resummation is shown to quench the too fast rise of the mini jet cross section and thereby obtain realistic total cross-sections.
