Book Description
The 20-year-old problem of the confinement and the resulting spectrum of the bound states is central to quantum chromodynamics (QCD). Many approaches have been tried starting from different points of view: the potential theory, the Bethe-Salpeter equation, string and flux tube models, bag models, vacuum structure, current algebra, lattice theory, and numerical simulations. Phenomenological assumptions and first-principle theoretical results or indications have been combined. Many partial successes have been attained, but a unified and comprehensive treatment is still lacking.In recent years, new attention has been given to the problem, both in terms of theoretical developments and for the purpose of evaluating the spectrum and other properties of the particles. In particular, attention has been focussed on areas like numerical simulations, the derivation of the potential, the use of the Bethe-Salpeter equation, the connection between the potential and the chiral symmetry approach.This workshop was an opportunity for a synthesis and a comparison of the different points of view.

Book Description
This book provides an update on our understanding of strong interaction, with theoretical and experimental highlights included. It is divided into five sections. The first section is devoted to the investigations into and the latest results on the mechanism of quark confinement. The second and third sections focus respectively on light and heavy quarks (effective field theories, Schwinger–Dyson approach and lattice QCD results). The fourth section deals with the deconfinement mechanism and quark–gluon plasma formation signals. The last section presents highlights of experiments, new physics beyond QCD, and nonperturbative approaches in other theories (strings and SUSY) that may be useful in QCD. Contents:Vortices, Confinement and Higgs Fields (R Bertle & M Faber)Hadronic Signature of Quark–Gluon Plasma (J Rafelski & J Letessier)Topology of Center Vortices (H Reinhardt)The Nonperturbative Quark-Gluon Vertex (J Skullerud et al.)Equivalence in Minkowski and Euclidean Field Theories (K M Maung et al.)Criterium for the Index Theorem on the Lattice (P Bicudo)Isospin Breaking in the Goldberger–Treiman Discrepancies (J L Goity & J Saez)Quantum Field Theory Approach to the Vacuum Replica in QCD (A V Nefediev & J E F T Ribeiro)Charm and Bottom Quark Masses from QCD Moment Sum Rules (M Eidemüller)Dilepton Production in Heavy-Ion Collisions: A Probe of Deconfinement (E Scomparin)Deuteron Photodisintegration at High Energy (F Ronchetti)Semianalytical Bounds on Spinless–Salpeter Energy Levels (R L Hall et al.)String Breaking and Monopoles in the 3D Abelian Higgs Model (M N Chernodub et al.)and other papers Readership: Researchers in high-energy, particle, theoretical, accelerator and experimental physics.

Book Description
This conference is the ninth in a biennial series dedicated to QCD and strong-interaction dynamics. Plenary talks cover both experiments, including the latest LHC results, and the most recent theoretical developments on hadron spectroscopy, lattice calculations, confinement and deconfinement. Parallel sessions are devoted to: Vacuum structure and confinement, light and heavy quarks, deconfinement, QCD and new Physics as well as nuclear and astroparticle Physics.

Book Description
This volume features papers presented at the 7th Conference on Quark Confinement and the Hadron Spectrum. It covers the up-to-date research done in the physics of quarks and their role as ultimate constituents of matter. It will be of interest to all theoreticians and experimentalists working in these areas.

Book Description
The confinement mechanism of the quarks in QCD is one of the most challenging and open problems in physics. Confinement is a nonperturbative phenomenon, and a definite way to handle it has not yet been found in field theory. There are lattice calculations that can produce the low-lying states of the spectrum and ?measure? many important physical quantities, but nevertheless the development of analytical techniques is of extreme importance for understanding the physics involved in confinement. In this respect it is important to test the results obtained directly from the theory (Bethe-Salpeter kernel, effective Hamiltonians, quark potential, etc.) on the spectrum, form factors and decays of bound states of quarks and gluons, and to relate them to the results of lattice theory.In this book, the question of the confinement mechanism is addressed; explanations in terms of monopoles, instantons and dyons are reviewed and the connection with duality is discussed.

Book Description
This book makes a global survey of nonperturbative aspects of quantum chromodynamics (QCD) from the viewpoints of mathematical, elementary-particle and hadron physics, including recent lattice-QCD results. It presents current, important progress in the following areas: the quark confinement mechanism, dynamical chiral-symmetry breaking, topologies in QCD (instantons, monopoles, vortices), SUSY QCD, nonperturbative methods (1/Nc, ladder QCD, AdS/CFT), QCD phase transition at finite temperature and density, quark-gluon plasma, and so on. For recent topics, the book also includes the experimental discovery of the penta-quark particle, the newest information on the QGP creation experiments, and theoretical progress on the baryonic three-quark potential and the high-density QCD.The proceedings have been selected for coverage in:• Index to Scientific & Technical Proceedings® (ISTP® / ISI Proceedings)• Index to Scientific & Technical Proceedings (ISTP CDROM version / ISI Proceedings)• CC Proceedings — Engineering & Physical Sciences
