High energy electroproduction off complex nuclei — •Thomas Falter, Wolfgang Cassing, Kai Gallmeister, and Ulrich Mosel — Institut für Theoretische Physik, Universität Giessen, 35392 Giessen, Germany

We investigate hadron formation in high energy electroproduction off complex nuclei in the framework of a BUU transport model. Our approach [1-3] combines a quantum mechanical treatment of the photon’s initial state interactions with a semi-classical coupled channel simulation of the hadronic final state interactions. This allows us to study different hadronization scenarios at JLab, HERMES and EMC energies and to draw conclusion about the space-time picture of hadron formation.
