| 英文摘要 | The nonlinear Dokshitzer-Gribov-Lipatov-Altarelli-Parisi (DGLAP) evolution equations with parton recombination corrections are used to dynamically evaluate the proton's parton distribution functions starting from a low scale mu(2), where the nucleon consists of valence quarks. We find that the resulting negative nonlinear corrections can improve the perturbative stability of the QCD evolution equation at low Q(2). Our resulting parton distributions, with four free parameters, are compatible with the existing databases. This approach provides a powerful tool to connect the quark models of the hadron and various nonperturbative effects at the scale mu(2) with the measured structure functions at the high scale Q(2) >> mu(2). |
