Combined analysis of diffractive and inclusive structure functions in the semiclassical framework

TL;DR

This paper presents a unified semiclassical framework to analyze both diffractive and inclusive structure functions in small-x deep inelastic scattering, using a model for color field averaging that aligns with DGLAP results at high Q^2.

Contribution

It introduces a specific model for averaging over color field configurations, enabling simultaneous calculation of diffractive and inclusive structure functions at low scales.

Findings

Good agreement with experimental data at high Q^2

Unified description of diffractive and inclusive processes

Model successfully reproduces structure functions at low Q^2

Abstract

Small-x DIS is described as the scattering of a partonic fluctuation of the photon off a superposition of target color fields. Diffraction occurs if the emerging partonic state is in a color singlet. Introducing a specific model for the averaging over all relevant color field configurations, both diffractive and inclusive parton distributions at some low scale Q_0^2 can be calculated. A conventional DGLAP analysis results in a good description of diffractive and inclusive structure functions at higher values of Q^2.
