Soft Color Fields in DIS at low x and low Q^2

TL;DR

This paper explores two approaches to deep inelastic scattering at low x and Q^2, utilizing soft color fields: a dual-Pomeron model and a semiclassical gluon density calculation.

Contribution

It introduces a dual approach combining a Pomeron model and a semiclassical gluon density method to study DIS at low x and Q^2, emphasizing soft color fields.

Findings

The Pomeron model fits low x data with two trajectories.

The semiclassical approach determines gluon density at NLO.

Both methods highlight the role of soft color fields.

Abstract

Two complementary approaches to DIS at low $x$ and low $Q^2$ are presented. In the first case we apply a model containig two Pomeron trajectories. In the second case we determine the gluon density in the semiclassical treatment at next-to-leading order. Both approaches rely on the concept of soft color fields.
