Abstract

To get some insight into the role of the gluon field in the recent “proton spin crisis”, the UA(1) Goldberger-Treiman relation is rederived on the basis of some specific effective lagrangrians which incorporates the axial anomaly of QCD. This model analysis indicates “quark spin screening” interpretation of the U A charge due to a nonperturbative effect of axial anomaly.
