Abstract: (APS)
Polarized parton distribution functions for a hadron target are defined in terms of gauge-invariant correlation functions. The polarized gluon contribution to the g1 structure function of the nucleon is computed using the modified minimal-subtraction scheme as a simple example of the calculational method. The gluon contribution to the integral of the g1 structure function is shown to vanish.- nucleon: structure function
