摘要：

New precise measurements of the neutral current cross section at HERA are presented in different Q(2) regimes. In the photoproduction limit the total gammap cross section is found to be in agreement with the universal soft Pomeron prediction. At medium scales 1.5 less than or equal to Q(2) less than or equal to 150 GeV2 both the F-2 and the F-L structure functions are determined. These data are well described by NLO pQCD. The gluon density in the proton has been extracted from the scaling violation of F-2 at low x. The transition between the two regimes occurs at around Q(2) similar or equal to 1 GeV2.
