Experimental data on the single-spin asymmetry and their interpretations by the chromomagnetic string model

摘要

An attempt to interpret the various existing experimental data on the single-spin asymmetries in inclusive pion production by polarized proton and antiproton beams is made. As the basis of analysis, the chromomagnetic string model is used. A whole measured kinematic region is covered. The successes and failures of such an approach are outlined. The possible improvements of the model are discussed.
