Minijets, soft gluon resummation and photon cross-sections

TL;DR

This paper compares models of high-energy photon-photon cross-sections, revealing that photon-photon interactions increase more rapidly with energy than purely hadronic processes like proton-proton collisions.

Contribution

It provides a comparative analysis of different models for photon-photon cross-sections and highlights their distinct high-energy behaviors.

Findings

Photon-photon cross-section rises faster than hadronic ones.

Model comparisons show differing energy dependence.

Photon interactions exhibit unique high-energy characteristics.

Abstract

We compare the high energy behaviour of hadronic photon-photon cross-sections in different models. We find that the photon-photon cross-section appears to rise faster than the purely hadronic ones (proton-proton and proton-antiproton).
