Determining the Strong Coupling Constant from Experimental Data in QCD

This study by S. Atashbar-Tehrani and Ali N. Khorramian from Semnan University and the School of Particles and Accelerators explores the determination of the strong coupling constant using available experimental data. The work highlights the motivation behind this study, analyzes the energy dependence of the running coupling, and examines non-singlet structure functions within Quantum Chromodynamics (QCD). Fit results for both unpolarized and polarized cases are presented, culminating in significant conclusions drawn from fitting world data up to next-to-next-to-leading order (NNLO) and beyond.
