Quark Propagation and Hadron Formation in the Nucleus

The preliminary results are presented for Jefferson Lab experiment E02-104 which was performed in the CLAS detector at Thomas Jefferson National Accelerator Facility. During the experiment, data on semi-inclusive production of hadrons in deep-inelastic scattering of a lepton off nuclei were acquired. These data provide important information about the space-time development of in-medium hadronizaton as well as give an opportunity to investigate the fragmentation processes in the nuclear medium. Transverse momentum broadening and hadronic multiplicity ratios for positively charged pions were measured as multidimensional functions of kinematic variables from different nuclear targets.
