Gluon Polarization In Nucleon
Abstract
In the context of the so-called valon model, we calculate $\frac{δg}{g}$ 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 $\frac{δg}{g}$ in the measured kinematical region should not be interpreted as $δg$ being small. In fact, $δg$ itself at small x, and the first moment of the polarized gluon distribution in the nucleon, $Δg(Q^2)$, are large
