Abstract
We have generalized the approach of Brodsky et al. for the intrinsic charm quark distribution in the nucleons to the light-quark sector involving intrinsic u-,d-,s and s- sea quarks. We compare the calculations with the existing d--u-, s+s-, and u-+d--s-s- data. The good agreement between the theory and the data allows the extraction of the probabilities for the |uuduu-〉, |uuddd-〉, and |uudss-〉 five-quark Fock states in the proton. We also calculate the x-dependence of the intrinsic charm after taking into consideration the QCD evolution of the intrinsic quark distribution.
