Pomeron Physics And Qcd

This page intentionally left blank Pomeron Physics and QCD This book describes the underlying ideas and modern developments of Regge theory. It confronts the theory with a huge variety of experimental data and with quantum chromodynamics. The book covers forty years of research and provides a unique insight into the theory and its phenomenological development. It provides comprehensive coverage of the various different theoretical approaches and considers the key issues for future theory and experiment. The authors review experiments that suggest the existence of a soft pomeron and give a detailed description of attempts to describe this through nonperturbative quantum chromodynamics. They suggest that a second, hard pomeron is responsible for the dramatic rise in energy observed in deep inelastic lepton–nucleon scattering. The two-pomeron hypothesis is applied to a variety of interactions and is compared with perturbative quantum chromodynamics, as well as with the dipole approach. This book will be a valuable reference for theoretical and experimental particle physicists all over the world. It is also suitable as a textbook for graduate courses in particle physics, high-energy scattering, QCD and the standard model. sandy donnachie obtained his PhD from the University of Glasgow in 1961.
