[en] Hadronization is the process through which partons, created in an elementary reaction, turn into hadrons. This phenomena has been studied for decades, however, the space-time features of this fundamentally non-perturbative process is not clearly understood. Semi-inclusive measurements of deep inelastic electron scattering from nuclei provide a unique testing ground to study the process of hadron formation. The space-time features and the nuclear dependence of quark propagation and hadronization can be extracted by comparing the production of various hadronic species from a number of target nuclei under different kinematic conditions. The CLAS experiment E02-104 was run with a variety of nuclear targets using a 5 GeV beam energy. The goal of this experiment is to measure observables related to propagation of a quark through cold nuclear matter.
