Azimuthal correlation in DIS

TL;DR

This paper introduces a new angular correlation observable in deep inelastic scattering (DIS), analyzes its distribution in the small observable region, and applies perturbative resummation with non-perturbative corrections.

Contribution

It presents a novel angular correlation in DIS and provides a detailed theoretical analysis including resummation and power corrections.

Findings

Resummed distribution at single logarithmic accuracy.

Estimated leading non-perturbative power corrections.

Characterized behavior of the new observable in the small region.

Abstract

We introduce a new angular correlation in DIS process and study its differential distribution in the region in which the observable is small. We perform a perturbative resummation at single logarithmic accuracy and estimate leading non-perturbative power corrections.
