How large is the anomalous contribution to the proton spin?

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

The definitions of parton polarized distributions contained in the literature are critically analyzed. It is shown that in the chiral limit the contribution of «anomalous» Dirac sea to the proton spin is exactly one third of the total quark contribution.
