Saturation model of DIS : an update

TL;DR

This paper updates the saturation model of deep inelastic scattering (DIS) by fitting recent low-x data with the GBW model and its modifications, confirming its robustness and key features like the saturation scale.

Contribution

The paper provides an updated fit of the GBW saturation model to recent DIS data, maintaining core elements while adjusting parameters for improved accuracy.

Findings

Model fits recent low-x data well

Saturation scale remains a key element

Parameters are slightly modified for better fit

Abstract

We present the results of new fits to the recently extracted data on $F_2$ at low $x$ with the GBW saturation model and its modification to cover high values of $Q^2$. We find that the model stands the test of time and gives a good description of the data with slightly modified parameters. All the essential elements of the model, especially the saturation scale, are retained.
