Quarks, Symmetries and Strings is a book that reflects the rich diversity of current research in physics: it describes quantum chromodynamics, quark phenomenology, superstring theory, supersymmetry, matrix models, statistical methods, superconductivity and neural networks. The book also reflects the diversity of Dr Bunji Sakita's scientific work. Dr Sakita has made seminal contributions in many of these areas. The book celebrates the many path-breaking ideas he pioneered which still cross-fertilize many of the most active areas of current research.

This book addresses major issues facing postal and delivery services throughout the world. Worldwide, there is currently a considerable amount of interest in postal and delivery economics. The industry is in a state of near crisis and drastic change is needed. The European Commission and member States are still wrestling with the problem of how to implement entry liberalization into postal markets, how to address digital competition, and how to maintain the universal service obligation (USO). The Postal Accountability and Enhancement Act of 2006 in the U.S. has perhaps created and exacerbated the problems faced by USPS. Post Offices (POs) have been slow to address the threat of electronic competition. On the other hand, e-commerce presents opportunities for POs to expand their presence in parcel delivery and perhaps help finance or redefine the USO. A major aim of this book is to address strategies POs can use to reinvent themselves for the digital age.This book compiles original essays by prominent researchers in the field, which will be selected and edited from papers presented at the 25th Conference on Postal and Delivery Economics held in Barcelona, Spain, May 24-27, 2017. That conference, and this volume, commemorates the memory of Michael Crew who organized twenty-four prior conferences and co-edited previous conference volumes. This book is a useful tool not only for graduate students and professors, but also for postal administrations, consulting firms, and Federal Government departments.

Aimed at graduate students and researchers in theoretical physics, this book presents the modern theory of strong interaction: quantum chromodynamics (QCD). The book exposes various perturbative and nonperturbative approaches to the theory, including chiral effective theory, the problems of anomalies, vacuum tunnel transitions, and the problem of divergence of the perturbative series. The QCD sum rules approach is exposed in detail. A great variety of hadronic properties (masses of mesons and baryons, magnetic moments, form factors, quark distributions in hadrons, etc.) have been found using this method. The evolution of hadronic structure functions is presented in detail, together with polarization phenomena. The problem of jets in QCD is treated through theoretical description and experimental observation. The connection with Regge theory is emphasized. The book covers many aspects of theory which are not discussed in other books, such as CET, QCD sum rules, and BFKL.

It has been well recognized that the study of the excitations of the nucleon can shed light on the nonperturbative aspects of QCD. New opportunities for such study will be opened in the next few years with the commissioning of experiments in Hall B of the Continuous Electron Beam Accelerator Facility (CEBAF) at the Thomas Jefferson National Accelerator Facility (JLab). Photo- and electroproduction studies of single and double pions, rhos, omegas, and kaons will be conducted with unprecedented precision. The Hall B CLAS detector is a major step forward, promising to provide kinematically complete measurements of cross sections and spin observables. The task of extracting new insights from such detailed measurements will require close coordination between experimental and theoretical physicists.To help optimize this interface between theory and experiment, a joint CEBAF/INT workshop was held at the Institute of Nuclear Theory in Seattle, September 9-13, 1996. The foci of the 1996 workshop included: N ā†’ Nāˆ— transition form factors as predicted by QCD-inspired models and their experimental consequences; theoretical techniques employing QCD sum rules, perturbative QCD, and lattice QCD; reaction theories of photo- and electro-production of mesons; theoretical issues in the eta meson, vector meson, and two-pion production channels; progress in developing amplitude analyses for the available and expected data; the relationship between the Hall B program and those of other new experimental facilities.This proceeding will serve readers as both a current perspective on the field and a guide to future experimental and theoretical research directions.

This book is devoted to the investigation of the strongly interacting hadrons ? to a quark model operating with effective color particles, constituent quarks, massive effective gluons and diquarks. The study of strong interactions based on effective constituent particles requires a solid ground of experimental data, which we now have at our disposal with the serious progress made in the investigation of hadrons, especially meson states.The present understanding of QCD applied to strong interactions can be distorted by prejudices. Therefore, the way followed by the quark model is to rely on the experiment and to restore the effective Hamiltonian on the basis of QCD on the one hand, and, on the other, of the spectral integral method.Baryon-baryon and antibaryon-baryon interactions are studied with the purpose of unambiguous applications of the written formulae to the interpretation of experimental data ? to the observation of new meson and baryon resonances. The technique used is the spin-orbital momentum expansion of the amplitude. This method is our basic approach to the proper treatment of experimental data. The photon-induced reactions are also considered and the problem of form factors is discussed.

An Introduction to Quantum Field Theory is a textbook intended for the graduate physics course covering relativistic quantum mechanics, quantum electrodynamics, and Feynman diagrams. The authors make these subjects accessible through carefully worked examples illustrating the technical aspects of the subject, and intuitive explanations of what is going on behind the mathematics. After presenting the basics of quantum electrodynamics, the authors discuss the theory of renormalization and its relation to statistical mechanics, and introduce the renormalization group. This discussion sets the stage for a discussion of the physical principles that underlie the fundamental interactions of elementary particle physics and their description by gauge field theories.
