# Nuclear configurational entropy of the energy-energy correlation in $e^+e^-$ annihilation processes

## TL;DR

This paper investigates the nuclear configurational entropy of the energy-energy correlation in electron-positron collisions, linking critical points to hadron scattering angles and matching phenomenological data using advanced QCD resummation techniques.

## Contribution

It introduces the analysis of nuclear configurational entropy in $e^+e^-$ processes within QCD, connecting critical points to scattering angles with high-precision phenomenological agreement.

## Key findings

- Critical points of nuclear configurational entropy match the scattering angles.
- The approach accurately reproduces phenomenological data.
- Uses next-to-next-to-leading logarithmic resummation in QCD.

## Abstract

In this paper the nuclear configurational entropy of the energy--energy correlation function is scrutinized, in $e^+e^-$ collisions to hadrons in the back-to-back region, within the QCD perturbative theory. The critical points of the nuclear configurational entropy concept, in the hot nuclear system, is shown to correspond to the critical angle between the two scattered hadrons, corroborating with phenomenological data with great accuracy. The main tools employ the main coefficients of the soft-gluon resummation formula, taking into account logarithmically enhanced contributions up to next-to-next-to-leading logarithmic accuracy.
