Proton structure measurements at high Q2 and x, performed by the HI and ZEUS
Collaborations at the HERA accelerator, are reviewed. Neutral and charge current
deep inelastic scattering cross sections and structure function measurements are
presented. A new method employed to measure the NC cross section up to Bjorkenx
values equal to one is described. The review also discusses the ZEUS-JETS PDF
fits which include jet data giving direct access to the gluon densities. An estimate
on the impact of HERA II data on the PDFs and their influence on the LHC
measurements are mentioned.
