Title: Deep Inelastic Lepton-Nucleon Scattering at HERA
Speaker: Paul Newman (Birmingham)
Abstract
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.
