Book Description
Experiments using highly polarized intense beams and targets, and theoretical studies of spin and polarization phenomena, are now providing us with numerous additional details of the electroweak and strong interactions and the structure of matter. The spin structure of the nucleon has been measured over wide ranges of kinematic variables, and the cross sections have been calculated to several orders in perturbative field theory. At present, the influence of the higher twist contributions, the gluon spin, and the quark orbital angular momentum are under scrutiny. Quantum chromodynamics (QCD) captures a lot of our experimental knowledge of hard polarized scattering processes. Can our understanding of such processes within QCD be further improved?Hyperons produced in high energy reactions show how puzzling strong interactions between hadrons still are. Spin observables in experiments at intermediate energy are used to test parity and charge symmetries. Will they also reveal, at low energy, a violation of time reversal symmetry? We are on the verge of using parity violation measurements at intermediate electron scattering energies to determine the amount of strange quark contributions to the neutral weak form factor of the nucleon. The polarization of the sea quarks is expected to be measured soon in W± decays produced in high energy polarized proton interactions. Will the jets in polarized Z⁰ decays show a definite handedness? These and many other topics are discussed in these proceedings.

Book Description
Vladimir Naumovich Gribov was one of the most outstanding theorists, a key figure in the creation of the modern elementary particle physics. His many discoveries are famous and well accepted by the physics community (Gribov-Regge theory of high energy hadron interactions, Gribov vacuum pole — Pomeron, Reggeon field theory, parton evolution equations, neutrino oscillations, Gribov copies in non-Abelian gauge field theories, etc.); Some of his ideas look unacceptable and strange at the first glance. Even at the second glance.Nowadays, under the weight of new theoretical developments and experimental results, his ideas are receiving the recognition they deserve. The Gribov Memorial Workshop, organized on his 75th birthday in Budapest, Hungary in 2005, clearly demonstrated the wealth and fertilization force of his ideas. Close colleagues, younger followers, world experts of the quark-hadron world have gathered together to display new angles of the Gribov heritage. And to remember the personality of a great man.This book collects the talks presented at, and contributed to, the Gribov-75 Memorial Workshop.

Book Description
The “Physics in Collision” conference aims to provide an overview of the main topics of high energy physics. This annual international meeting consists of three days of exclusive review talks, given by invited speakers. As a result, it has taken on a unique character, ideal for those who wish to be brought up to date on the current status of particle physics.

Book Description
The measurement of spin-polarization observables in reactions of nuclei and particles is of great utility and advantage when the effects of single-spin sub-states are to be investigated. Indeed, the unpolarized differential cross-section encompasses the averaging over the spin states of the particles, and thus loses details of the interaction process. This introductory text combines, in a single volume, course-based lecture notes on spin physics and on polarized-ion sources with the aim of providing a concise yet self-contained starting point for newcomers to the field, as well as for lecturers in search of suitable material for their courses and seminars. A significant part of the book is devoted to introducing the formal theory—a description of polarization and of nuclear reactions with polarized particles. The remainder of the text describes the physical basis of methods and devices necessary to perform experiments with polarized particles and to measure polarization and polarization effects in nuclear reactions. The book concludes with a brief review of modern applications in medicine and fusion energy research. For reasons of conciseness and of the pedagogical aims of this volume, examples are mainly taken from low-energy installations such as tandem Van de Graaff laboratories, although the emphasis of present research is shifting to medium- and high-energy nuclear physics. Consequently, this volume is restricted to describing non-relativistic processes and focuses on the energy range from astrophysical energies (a few keV) to tens of MeV. It is further restricted to polarimetry of hadronic particles.

Book Description
This book is devoted to the polarization (spin) physics of high energy particles and contains three parts. The first part presents the theoretical prefaces of polarization in the particle physics for interpretations, predictions and bases for understanding the following two parts. The second part of the book presents the description of the essential polarization experiments including the recent ones. This part is devoted to the innovative instrumentations, gives the parameters of the polarized beams, targets, polarized gas jets and polarimeters. The third part of the book concentrates on the important achievements in polarization physics. The book can be used in lectures on nuclear and particle physics and and nuclear instruments and methods. As supplementary reading this book is useful for researchers working in particle and nuclear physics.

Book Description
One of the most fundamental questions in understanding strong interaction is whether or not quarks and gluons play a significant role in nuclear systems. At high densities we need to explore the existence and nature of a deconfinement phase transition. At lower densities we wish to study the changes in the properties of a hadron particle as mass and electroweak form factors, when it is immersed in nuclear matter. Finally, we may even ask whether the internal structure of the nucleon plays a role in the binding and properties of finite nuclei.On the theoretical side the issues raised here are of concern to a very broad community, from those working in traditional many-body physics, to those building effective field theories, to those working in lattice QCD. Experimentally, there are many accelerators, mature, new and planned, which can offer insight into this field — from SLAC to HERA, COSY, CELSIUS and TJNAF. This workshop brought together key figures from all areas of theoretical and experimental physics concerned with this fundamental problem.

Book Description
The High Energy Accelerator Conference has always been the monitor of the state of the art and the new trends in planning, construction and operation of large particle accelerators. It is held every three years. The 1992 conference is devoted to High Energy Hadron Accelerators and Colliders, Linear Colliders, e⁺e⁻ Storage Rings and related Technologies for these machines. In addition to status reports and contributed papers, the program features twelve survey talks which include summaries of individual poster papers.
