Energy dependence of the single spin asymmetries in inclusive pion production processes

Recent data from the E925 Collaboration at Brookheaven National Laboratory show a significant energy dependence of the single-spin left-right asymmetry in inclusive hadron production in hadron-hadron collisions. We analyze the experimental results and show that the observed energy dependence can be reproduced naturally in the picture proposed in a previous Letter. We fix all the parameters at the Fermilab E704 energy and calculate the asymmetry at the BNL E925 energy. We compare the results with the data and make predictions for experiments at even higher energies
