Comparison Of Exclusive Reactions At Large Momentum Transfer

During the past decade considerable literature has appeared on the topic of exclusive reactions at high momentum transfer. Two important recent developments offer the possiblity of experimentally testing the theoretical ideas in a systematic way. These are the potential CEBAF energy upgrades and the proposed 15 - 30 GeV European Electron Accelerator, ELFE.This volume records the state-of-the-art in studying exclusive reactions at high momentum transfers and establishes a common body of knowledge to be shared by all. There is some emphasis on the use of perturbative calculations to connect hadron structure to experimental measureables and other topics, including color transparency, the use of QCD sum rules and experiemental data.

This book will be of great interest to advanced students and researchers in the area of high energy theoretical physics. Being the most complete and updated review volume on Perturbative QCD, it serves as an extremely useful textbook or reference book. Some of the reviews in this volume are the best that have been written on the subject anywhere.

Stanford University hosted the XIX International Symposium on Lepton and Photon Interactions at High Energies on August 9 - 14, 1999, at the Law School on the Stanford University Campus, the site of the previous Symposia. This volume constitutes the proceedings of the Symposium.

Annotation. The Proceedings include talks given at the 4th Workshop on Exclusive Reactions at High Momentum Transfer at Jefferson Lab, Newport News, VA USA, the world's leading facility performing research on nuclear, hadronic and quark-gluon structure of matter. Exclusive reactions are becoming one of the major sources of information about the deep structure of the nucleons and other hadrons. The workshop focused on the application of a variety of exclusive reactions at high momentum transfer, utilizing unpolarized and polarized beams and targets, to obtain information about nucleon ground state and excited state structure at short distances. This is a subject which is central to the programs of current accelerators and especially planned future facilities. The topics include: generalized parton distributions, deeply virtual Compton scattering, deeply virtual meson production (DVMP), transverse structure of hadrons (TMD), hadron form factors - elastic and transition, quantum chromodynamics (perturbative, non-perturbative, lattice calculations), and physics to study at an Electron Ion Collider.
