Second Order Twist Contributions to the Balitsky-Kovchegov Equation at small-x: Deterministic and Stochastic Pictures

TL;DR

This paper investigates second order twist corrections in a dipole interaction model at small-x, highlighting differences between deterministic and stochastic approaches in high N_C limit.

Contribution

It introduces a detailed analysis of second twist corrections within both deterministic and stochastic frameworks at high N_C, emphasizing their differing impacts.

Findings

Second twist corrections are more significant in stochastic models.

Stochastic effects influence the importance of higher twist contributions.

The study provides insights into dipole interactions at small-x in high-energy QCD.

Abstract

We study the second order twist corrections to a toy model of a dipole-dipole interaction in the context of a both deterministic and stochastic effects. This work is done in the high $N_C$ limit in the Bjorken picture. We show that the correction to the second twist terms of the stochastic picture suggest additional importance of the second twist correction in the stochastic model as compared to the deterministic model.
