Abstract
This thesis aims to explore the running of the strong coupling constant through the analysis of the Primary Lund plane for charged jets from proton-proton collisions at √s=13.6 TeV detected by the ALICE detector during the LHC Run 3 in 2022. First, the quality and reliability of the data used in this analysis have been ensured through a detailed track quality assurance. Subsequently, the first Primary Lund plane for Run 3 data has been constructed and the Primary Lund plane density has been analyzed with the aim of extracting information on the jet substructures and, specifically, on the running of the strong coupling constant. Moreover, the results are compared with other experimental measurements.
