Constituent Quarkstructur and $F_2^p$ Data

Abstract

We have calculated the partonic structure of a constituent quark in the leading order in QCD for the first time and examined its ipmlications on the proton structure function, $F_2^p,datafromHERA.Itturnedoutthatalthoughqualitativelyitagreeswiththedatabutforafinerrefinementweneedtoconsideraninherentcomponentduetogluonswhichactasthebindingagentbetweenconstituentsquarksintheproton.Goodagreementwithnucleonstructurefunction,$F_{2}(x,Q^{2})$,forawiderangeof$x=[10^{-6} ,1]$and$Q^{2}=[0.5, 5000]GeV^{2}$ is reached. {\bf{PACS Numbers 13.60 Hb, 12.39.-x, 13.88 +e, 12.20.Fv}}
