The structure of the proton and NLO QCD fits
  HERA has provided a wealth of high precision structure function and jet production data, allowing considerable progress to be made in understanding the structure of the proton. In this paper, several of the most recent proton structure results from the H1 and ZEUS Collaborations at HERA are presented. These include results from NLO QCD fits, neutral current deep inelastic scattering and jet production at high transverse energy.
