Abstract: The new (p) over bar ((up arrow))p(up arrow) collider modes proposed for the HESR at GSI would provide new insights on the spin structure of the nucleon, even if only one of the two probes could be polarised. Drell-Yan processes are a powerful tool to access chirally odd parton distribution functions like transversity h(1)(x), without their convolution with fragmentation functions and without the suppression proper of the DIS experiments, in reactions were all the quarks taking part can be valence quarks. New insights on the relation of perturbative and non perturbative dynamics in hadron scattering could come in an earlier stage by the mean of the PANDA spectrometer and of the present HESR design. Spin asymmetries in hadron production and nucleonic form factors are discussed as well.
