Physics potential of polarized positrons at the Jefferson Laboratory

Charge symmetry in hadronic reactions, either verified or violated, appears to be in some circumstances a mandatory guide for model-independent understanding of the structure and dynamics at play. The recent demonstration of the PEPPo concept for the production of polarized positronsopens new physics perspectives at the Jefferson Laboratory. Polarized positronbeams, in complement to existing polarized electron beams, are shown to bring multi-Physics opportunities.
