Physics Results from the First Electron-Proton Collider Hera

Abstract

On the 31st of May 1992 the first electron-proton (ep) collisions were observed in the H1 and ZEUS experiments at the newly commissioned high energy collider HERA, in Hamburg, Germany. HERA is the first electron-proton collider in the world: 26.7 GeV electrons collide on 820 GeV protons, yielding an ep centre of mass system (CMS) energy of 296 GeV. Already the results from the first data collected by the experiments have given important new information on the structure of the proton, on interactions of a high energetic photons with matter and on searches for exotic particles. These lectures give a summary of the physics results obtained by the H1 and ZEUS experiments using the data collected in 1992 and 1993.KeywordsParton DistributionDeep Inelastic ScatteringGluon DistributionHard ScatteringZEUS CollaborationThese keywords were added by machine and not by the authors.
