This volume contains the proceedings of the Workshop on Physics with an Electron-Polarized Ion Collider (EPIC-99), jointly sponsored by the Indiana University Cyclotron Facility and Nuclear Theory Center, and the Institute for Nuclear Theory, University of Washington. It was held in Bloomington, Indiana, April 8-11, 1999. The purpose was to discuss important new physics phenomena which could be investigated with a high-luminosity asymmetric collider consisting of a beam of polarized electrons (with energy roughly 5 GeV), and a beam of polarized protons or other light ions of approximately 40 GeV energy. The Workshop brought together experts in the field who highlighted the unique potential for such a facility, and compared the prospects and challenges for this collider with present and proposed facilities around the world.The proceedings of this Workshop summarize our currently available knowledge on the physics potential for a polarized asymmetric collider. It provides a unique collection of information on the opportunities which such a facility would provide.
The QNP series of international conferences on Quarks and Nuclear Physics is by now a well established and highly respected forum where the most recent developments in the field are discussed and communicated. QNP 2006 is the forth edition of this biennial meeting. Selected and refereed original contributions of QNP 2006 have been published in The European Physical Journal A - Hadrons and Nuclei (EPJ A), while the present proceedings book, in addition to reprinting the articles published in EPJ A, further includes all other contributions selected and accepted by the organizing committee for publication and archiving.
This volume deals with both the experimental and theoretical aspects of meson physics; in particular, it presents new results. The main topics are: hadronic and electromagnetic meson production in various reactions; meson interaction with mesons, nucleons and nuclei; the structure of hadrons; mesons and fundamental symmetries; exotic systems. The book provides an overview of the current status of these areas, as well as of new developments, besides giving a preview of the forthcoming investigations.
For over thirty years bound states of gluons are an outstanding problem of both theoretical and experimental physics. Being predicted by Quantum-Chromodynamics their experimental confirmation is one of the foremost goals of large experimental facilities currently under construction like FAIR in Darmstadt. This thesis presents a novel approach to the theoretical determination of physical properties of bound states of two gluons, called glueballs. It uses the consistent combination of Schwinger-Dyson equations for gluons and ghosts and appropriate Bethe-Salpeter equations describing their corresponding bound-states. A rigorous derivation of both sets of equations, starting from an 2PI effective action is given as well as a general determination of appropriate decompositions of Bethe-Salpeter amplitudes to a given set of quantum numbers of a glueball. As an application example bound state masses of glueballs in a simple truncation scheme are calculated.

The aim of the Conference was to discuss recent results and perspectives on the theoretical and experimental investigation of the structure of free hadrons and hadrons in the nuclear medium, as well as the structure of hadronic matter both at normal and extreme conditions. The Volume is a useful update of the subject for theorists and experimentalists working in medium and high energy nuclear physics.
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.
There are four fundamental forces in nature: gravitational, electromagnetic, weak, and strong forces. The last two are sometimes referred to as nuclear forces. It is the main objective of high energy physics to explore these forces, and hopefully unify them into one fundamental theory. This goal has made high energy physics one of the most ambitious, attractive, challenging, and powerful areas of physics, and has attracted experts from other areas including pure and applied mathematics, and computer science. The MRST annual conference brings together senior and junor investigators and provides a friendly and stimulating atmosphere to discuss recent developments in high energy physics. A broad range of topics in high energy physics was covered in this conference, and therefore these proceedings will be very useful to both senior researchers as well as graduate students in high energy physics, nuclear physics, and computational physics, providing most recent ideas, techniques, and directions for future research in this field.
Physicists who wish to understand the modeling of confinement of quantum chromodynamics, as exhibited by dual superconductors, will find this book an excellent introduction. The author focuses on the models themselves, especially the Landau--Ginzburg model of a dual superconductor, also called the Dual Abelian Higgs model.
