摘要
Phenomenological studies on the proton structure function F^2 have beencarried out to investigate the behavior of F^2, i.e. its x and Q^2 dependence,in the transition from the deep-inelastic scattering region (Q^2 1 GeV^2) tothe photoproduction region (Q^2 approx. 0 GeV^2). An overview of variousresults of F^2 at low Q^2 is given. To quantify the behavior of F2 at low Q^2,the derivatives dln(F^2)/dln(x) for fixed Q^2 and dF^2/dlog(Q^2) for fixed xhaven been determined and compared to expectations within the framework ofperturbative and non-perturbative QCD. Furthermore, the derivatives werecompared to results of the total inclusive diffractive cross-section andvector-meson production. An interpretation of inclusive ep results is given inthe framework of the GVD/CDP picture with special emphasis on the limit of Q^2--> 0 for fixed W^2 and x --> for fixed Q^2.
