Theoretical interpretation of polarized leptoproduction data
- Conference date: 15−17 Nov 1990
- Location: University Park, PA (USA)
We examine the role of quarks and gluons in polarized leptoproduction in connection with the famous EMC experimental result. The gluon contribution generated by the axial anomaly is shown to have a well defined physical meaning and its gauge invariance properties are fully clarified. We also emphasize the role of the ghost contribution in the generalized Goldberger‐Treiman relation.
