Updated Determination of Ellis-Jaffe Sum Rules up to $\rm N^{3}LO$ QCD corrections

2024 · arXiv (Cornell University)

In this paper, we explore the properties of the Ellis-Jaffe Sum Rule (EJSR) by employing the Principle of Maximum Conformality (PMC) approach to address its perturbative part up to next-to-next-to-next-to-leading order ($\rm N^{3}LO$) QCD contributions. …
