Low x Physics At HERA

TL;DR

This paper discusses low x physics at HERA, highlighting how the energy dependence of scattering processes becomes harder as the probe's transverse size decreases, based on data from H1 and ZEUS.

Contribution

It provides an analysis of low x physics phenomena at HERA, emphasizing the increasing hardness of energy dependence in scattering processes with decreasing transverse size.

Findings

Energy dependence of scattering becomes harder at low x

Diffractive processes show increased hardness with smaller probe size

Data from H1 and ZEUS support these observations

Abstract

Data on low x physics from H1 & ZEUS are presented and their interpretation discussed. The focus is on the increasing hardness of the energy dependence of inclusive virtual-photon proton scattering and certain diffractive processes as the transverse size of the probe decreases.
