Updated Determination of Ellis-Jaffe Sum Rules and Extraction of Quark
Spin Content
In this paper, we explore the properties of the Ellis-Jaffe Sum Rule (EJSR) in detail, employing the Principle of Maximum Conformality (PMC) approach to address its perturbative QCD contribution including next-to-next-to-next-to-leading order ($\rm N^{3}LO$) QCD corrections. Using the PMC, we attain a precise perturbative QCD approximate for the EJSR, without …
