โฆ Synopsis
The results of inclusive charged and neutral current measurements at HERA are shown. The results cover a Q2 range of 100 to 30 000 GeV2 and Bjorken 2 between 0.0013 and 0.65. Measurements of the proton structure functions I?2 and x?;; are made, as well as the extraction of FL in the range 110 < Q2 <700 GeV'. Parton distribution functions are extracted from these data in a next to leading order QCD analysis.

A precise proton structure function F2 at low x is measured. The data is interpreted in the framework of QCD with an extraction of gluon density xg. The charm contribution to F2 is determined in an extended kinematic range. Neutral and charged current crosssections at high Q2 axe also measured and c
HERA is the natural extension of an impressive series of fixed-target lepton-nucleon scattering experiments. The increase of a factor ten in center-of-mass energy over that available previously has allowed the discovery of several important results, including the large number of slow partons in the
