Study of $\Lambda$ SIDIS in the Current and Target Fragmentation Regions using CLAS

ORAL

Abstract

The hadronization or fragmentation process defines the transformation of the energetic struck quark into color-neutral hadrons. The latter is an effective probe of the confinement mechanism that entails all color charge to be asymptotically resolved into color singlet subsystems. Yet, the hadronization study yields a scan of the two characteristic time-scales involved in the process. These time-scales are significant to elucidate our understanding of the color-neutralization and subsequent non-perturbative formation of the observed hadrons. This talk will report the first-ever analysis of the semi-inclusive deep inelastic scattering (SIDIS) of $\Lambda$ hyperon in the current and target fragmentation regions using various CLAS6 5-GeV nuclear targets data-sets. Results on multiplicity ratios and the transverse momentum broadening will be presented. The results from this work along with other CLAS6 meson studies are pioneering the upcoming CLAS12 color propagation measurements.
