Extraction of various five-quark components of the nucleons

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.
