Small x QCD and Multigluon States: a Color Toy Model

TL;DR

This paper introduces a simplified toy model mimicking the color structure of the BKP system in QCD to study finite color corrections versus the planar limit.

Contribution

It presents a novel toy model with finite degrees of freedom that replicates the color interactions of the BKP system in high-energy QCD.

Findings

Finite number of color corrections are significant compared to the planar limit.

The toy model captures essential color dynamics of the BKP system.

Insights into the role of finite color effects in QCD processes.

Abstract

We introduce and study a toy model with a finite number of degrees of freedom whose Hamiltonian presents the same color structure of the BKP system appearing in the studies of QCD in the Regge limit. We address within this toy model the question of the importance of finite number of color corrections with respect to the planar limit case.
