Title: Deep Inelastic Lepton-Nucleon Scattering at HERA
Speaker: Paul Newman (Birmingham)
Data from the HERA collider experiments, H1 and ZEUS, have been fundamental to the rapid recent development of our understanding of the partonic composition of the proton and of QCD. This talk concentrates on the inclusive measurements of neutral and charged current cross sections, using the full available data taken to date. The present precision on the proton parton densities and the further requirements for future measurements at the Tevatron and LHC are explored. Focus is also placed on the region of low Q2 and x, where the `confinement' transition takes place from partons to hadrons as the relevant degrees of freedom and where novel or exotic QCD effects associated with large parton densities are most likely to be observed.
