Polarized Parton Distributions in the Valon Model

We calculated the polarized parton distributions in leading order approximation in QCD from valon model. Polarized structure function of the nucleon are analyzed in the polarized valon model in which a nucleon is assumed to be a bound state of three polarized valence quark cluster(valons). It is shown that the results of the model calculation agree rather well with the SMC and available experimental data . Our results for $Γ_{1}$ of hadron and deuteron are in good agreement with experimental data for some value of $Q^{2}$.

Basic Structure in Hadrons

We have calculated the Structure function a constituent quark in the NLO and from it we have derived the structure functions of hadrons. We found that perturbative generation of hadron structure falls short of conforming with data by a few percent. This is due to the presence of soft gluon and its radiation in the hadron. This contribution is modeled into our calculations. It is also responsible for the breaking of flavor symmetry in the nucleon sea.
