Book excerpt: This thesis describes the methods and results of the first measurement of the proton structure function F2 by the ZEUS collaboration. The ZEUS detector is one of two large general purpose detectors at the electron-proton colliding facility HERA located at DESY in Hamburg Germany. HERA provides collisions of 26.6 GeV electrons with 820 GeV protons, resulting in a center of mass energy an order of magnitude higher than previous fixed target electron scattering experiments. The kinematics at HERA allows the measurement of F2 in a region o f x ana Q2 phase space previously unexplored. A total integrated luminosity of 24.7 nb-1, collected during the fall of 1992, was used for the measurement of F2. The results reported here extend the measurement of F2 to lower values of x by two orders of magnitude. In the parton model the behavior of F2 at low x is highly dependent on the unknown gluon distribution and the absence of data leads to significantly different expectations of the neutral current cross sections at low x. A measurement of F2 at low x constrains the gluon distribution. The results show a strong rise at low x.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A first measurement of the radiative contribution to deep inelastic electron-proton scattering has been performed with the ZEUS detector at HERA. Results show consistency with predictions made by the HERACLES Monte Carlo program. New calibration and simulation of the far luminosity measurement system, including a photon calorimeter and two aerogel Cherenkov detectors, have been implemented. Both calibration and simulation were applied to tag photons produced in the initial state radiative process. These tagged events were used to perform measurements of the deep inelastic ep scattering reduced cross section down to momentum transfer squared, Q2 = 3.0 GeV2, a region normally inaccessible to ZEUS. A determination of the radiative contribution to deep inelastic scattering has aided in the measurement of the structure functions F2 and FL, which were simultaneously extracted in the kinematic region 8.0 GeV2

Available in PDF, EPUB and Kindle. Book excerpt: This workshop is the fourth of a series initiated in Durham (March 93), followed by Eilat (February 94) and Paris (April 95). The large interest and the great inflow of experimental data, coming mainly from HERA, are some of the reasons behind the decision to have this annual meeting, presently the most important one for this area of research. During the workshop, experimental results and theoretical aspects have been reported on subjects, which have been organised by working groups on: 1) hadron structure functions; 2) photoproduction and photon structure; 3) diffractive interactions; 4) hadronic final states; 5) spin effects in lepton nucleon scattering; 6) special session on theoretical advances. While the contributions to the working groups offer hot material for specialists, the reports by the conveners, as well as other contributions to the plenary sessions, offer to nonspecialists a complete overview of this research field.

This book was released on 1996-08-30 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: After about three decades of experimental and theoretical efforts, the structure of the nucleon (proton and neutron) is now fairly well understood based on quantum chromodynamics, but only if averaged over its spin. As the recent “proton spin crisis” revealed, we do not understand much about the nucleon structure when its spin is polarized to a specific orientation. We expect that our understanding on this challenging problem will soon be significantly improved by the RHIC-Spin and other experiments in the near future, as well as by the lattice- and perturbative-QCD theoretical calculations. The purpose of this symposium was to summarize the current understanding and discuss the future perspective of this problem with experimental and theoretical physicists from both high-energy and nuclear physics communities.The symposium covered the overview of the structure studies, updates on the experimental results from CERN, SLAC, DESY, FNAL, and KEK, future experiments at RHIC, and recent theoretical developments (18 presentations, 113 participants).
