Probing Hadronization Dynamics and Diquarks Structure via Lambda Production off Nuclei

ORAL · Invited

Abstract

Studies based on employing hard probes and pioneering processes such as semi-inclusive deep inelastic scattering (SIDIS) on atomic nuclei are potent in accessing medium modifications of their underlying structure, exploring the hadronization mechanisms, and studying Quantum Chromo-Dynamics confinement dynamics in the cold nuclear medium. Indeed, the study of the hadronization process in such a clean environment effectively probes the fragmentation mechanisms related to color propagation and hadron formation and, thus, its associated time-distance scales. In this talk, I will highlight recent hadronization results from Jefferson lab, focusing on the first-ever SIDIS study of Lambda hyperon in the current and target fragmentation regions. The new Lambda results could improve our understanding of quark-diquark correlations and open a new era of studies of the nucleon along light and strange baryon structures.
