A. M. Cooper-Sarkar
TL;DR
This paper utilizes HERA jet production data to improve the understanding of the gluon distribution inside protons and to precisely measure the strong coupling constant, demonstrating its variation with energy scale.
Contribution
It introduces a method to extract both the gluon parton distribution function and the strong coupling constant from HERA jet data, enhancing precision and understanding.
Findings
