摘要：

We discuss several technical problems which arise in the computation of the contribution induced by the chiral anomaly in the polarization of the proton. We adopt a nonperturbative approach which allows us to resolve issues of infrared regularization and gauge invariance. We analyze the anomalous contribution of both perturbative and nonperturbative gluon configurations and relate the former to the helicity of hard gluons measured in high-energy inclusive scattering. © 1990.
