    "abstract": "We discuss a few examples of structure functions for polarized,\nsemi-inclusive scattering processes to show the richness of structure. Then we\nindicate how polarization and particle production can be used to study the\nquark and gluon structure of hadrons going further than the well-known parton\ndensities and fragmentation functions. We also emphasize how single spin\nasymmetries in leptoproduction may shed light on explanations for single spin\nasymmetries in pion production in pp collissions.",
