Abstract: |
In the context of the so-called valon model, we calculate ±g
g and show that although
it is small and compatible with the measured values, the gluon contribution to the
spin of nucleon can be sizable. The smallness of ±g
g in the measured kinematical region
should not be interpreted as ±g being small. In fact, ±g itself at small x, and the ¯rst
moment of the polarized gluon distribution in the nucleon, ¢g(Q2), are large.
