Transverse Momentum Transfer and Low x Parton Dynamics at HERA

TL;DR

This paper introduces a transverse momentum transfer correlation as a new probe to distinguish between different models of parton dynamics in low-x deep-inelastic scattering, comparing theoretical expectations with Monte Carlo simulations.

Contribution

It proposes a novel correlation measure and evaluates its effectiveness in discriminating between models of parton dynamics at low x in deep-inelastic scattering.

Findings

The correlation measure can differentiate between uncorrelated and correlated models.

Monte Carlo simulations show varying predictions for different parton dynamics models.

The approach enhances understanding of parton behavior at low x.

Abstract

The transverse momentum transfer correlation is introduced as a sensitive probe that can be used to discriminate between models for parton dynamics in low-x deep-inelastic scattering. Expectations for uncorrelated models and models with short-range or long-range correlations are discussed and confronted to results obtained from the LEPTO and ARIADNE Monte Carlo simulations programmes.
