Title: Gluon Contribution To The Nucleon Spin

Abstract

Gluon polarization in Nucleon is evaluated in the valon representation of hadrons. It is shown that although {delta}g/g is small at the currently measured kinematics, it does not imply that the gluon contribution to the nucleon spin is small. In fact the first moment of gluon polarization in the nucleon, {Delta}g(Q{sup 2}), is sizable. We also notice that the majority of {Delta}g is concentrated at around x = 0.08.
