Colour transparency in hard exclusive reactions — •Murat M. Kaskulov, Kai Gallmeister, and Ulrich Mosel — Institut für Theoretische Physik, Universität Giessen, Germany

We present a microscopic approach to hadron attenuation and colour transparency in hard electromagnetic reactions off nuclei. Our results for (e,e′π⁺) off nuclei support the early onset of the pionic colour transparency observed at JLab. The model results for the colour transparency effect in semi-exclusive electroproduction of strangeness from nuclei will be presented. These results provide a base for similar effects of CBM at FAIR.
