Hadronization in Cold Nuclear Matter — •Kai Gallmeister and Ulrich Mosel — Institut für Theoretische Physik, Universität Giessen, Germany

We study the hadron attenuation measured in semi inclusive particle production at CLAS, HERMES and EMC within the semi classical transport model GiBUU. By comparing different scenarios for the hadronization we get information about the underlying space time picture. Also the data for exclusive pion and rho production off nuclei is described by our calculations. In addition, we also compare calculations for the production of charged pions by pion or proton beams off nuclei with recent data of the HARP collaboration for beam energies from 3 up to 13 GeV. While originally designed for calibrating the flux for neutrino induced experiments, the data from this experiment represents a valuable check for hadronization and final state interaction models.
