Abstract
Within the framework of a simple model, we study single-spin
asymmetries for pion production in hadron-hadron collisions at
high energies with one hadron polarized. The asymmetries are
generated via a mechanism of final- (initial-) state interactions.
For peripheral kinematics, we find nonzero asymmetries at the high-energy limit when the pion belongs to the
fragmentation region of the polarized proton. Numerical results and
comparison with existing experimental data are presented. We also
discuss the relationship with Odderon exchange phenomenology.
