Currents and Mesons


Book Description

Current and Mesons is the most recent publication in the Chicago Lectures in Physics series. The book presents Professor Sakurai's introduction to a new field of elementary particle physics which has become increasingly important in the past few years. It is based on a course given to his advanced graduate students in theoretical high-energy physics at the University of Chicago. The author begins with a brief review of SU (3). The major topics then treated are the divergence condition and current commutation relations, vector meson universality, PCAC and the Goldberger-Treiman relation, soft pion processes, and asymptotic symmetries and spectral-function sum rules. The book concludes with a discussion of notation and of normalization convention. Professor Sakurai's work deals with topics on which much of current discussion on the theory of elementary particles is focused. The material is designed for the advanced student who is seriously interested in doing original work, and as such provides a much needed introduction to the present literature in the field.




Quarks Bound by Chiral Fields


Book Description

The structure of light hadrons is dominated by the spontaneously broken chiral symmetry of the strongly interacting (QCD) vacuum. Low energy properties of light hadrons can be described in terms of quarks interacting with chiral fields. This book gives a comprehensive account of a large class of models which describe the restoration of chiral symmetry at high temperature and density, the effective interactions between quarks, mesons as solutions of the Beth-Salpeter equation, and baryons in terms of solitions which rotate in flavor space. An in-depth analysis of regularization is given, including regularization by delocalized fields. Symmetry conserving approximations are formulated using both path integral and Feynmann graph methods. The book's style is pedagogical and well-suited to graduate and Ph.D. students who want to learn the techniques used in present day research. It can also serve as a reference for research and lecture courses.




Mesons And Baryons: Systematization And Methods Of Analysis


Book Description

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.

Communication


Book Description

On contemporary communication in its various human and nonhuman forms Contemporary communication puts us not only in conversation with one another but also with our machinery. Machine communication—to communicate not just via but also with machines—is therefore the focus of this volume. Diving into digital communications history, Finn Brunton brings to the fore the alienness of computational communication by looking at network timekeeping, automated trolling, and early attempts at communication with extraterrestrial life. Picking up this fascination with inhuman communication, Mercedes Bunz then performs a close reading of interaction design and interfaces to show how technology addresses humans (as very young children). Finally, Paula Bialski shares her findings from a field study of software development, analyzing the communicative forms that occur when code is written by separate people. Today, communication unfolds merely between two or more conscious entities but often includes an invisible third party. Inspired by this drastic shift, this volume uncovers new meanings of what it means “to communicate.”
