This book was released on 2008-09-04 with total page 603 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This work originated in a series of lectures on meson and baryon ex cited states which I gave at the Stanford Linear Accelerator Center in the fall of 1962. The notes of these lectures were issued as a Stanford Uni versity report (SLAC-13) in March, 1963. In the fall of 1963, I gave a revised set of lectures on meson and baryon spectroscopy at Indiana University. In both cases, the talks were given primarily for experi mental physicists. In preparing the notes of these talks for pUblication, I have added some introductory material on pions, nucleons, kaons, and hyperons. My main emphasis is on the experimental facts concerning the spectros copy of the mesons and baryons and on the use of conservation laws in their interpretation. I have either mentioned briefly or omitted entirely explanations which depend on dynamical models. Although I have given a number of facts about the electromagnetic and weak decays of some mesons and baryons, I have not discussed the theory of these decays. This is not a comprehensive review of the subject of the strongly interacting particles, and the list of references is not complete. Also, I have not always devoted time to a subject in proportion to its impor tance, but have spent more time on topics which have particularly interested me. Nevertheless, I hope that I have provided a useful summary of the most important facts about the spectroscopy of the mesons and baryons.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis is an attempt to understand the properties of the protons, pions and other hadrons in terms of their fundamental building blocks. In the first chapter the author reviews several of the approaches that have already been developed. The Nambu-Jona-Lasinio model offers the classic example of a derivation of meson properties from a quark Lagrangian. The chiral quark model encodes much of the intuition acquired in recent decades. The author also discusses the non-linear sigma model, the Skyrme model, and the constituent quark model, which is one of the oldest and most successful models. In the constituent quark model, the constituent quark appears to be different from the current quark that appears in the fundamental QCD Lagrangian. Recently it was proposed that the constituent quark is a topological soliton. In chapter 2 the author investigates this soliton, calculating its mass, radius, magnetic moment, color magnetic moment, and spin structure function. Within the approximations used, the magnetic moments and spin structure function cannot simultaneously be made to agree with the constituent quark model. In chapter 3 the author uses a different plan of attack. Rather than trying to model the constituents of the baryon, he begins with an effective field theory of baryons and mesons, with couplings and masses that are simply determined phenomenologically. Meson loop corrections to baryon axial currents are then computed in the 1/N expansion. It is already known that the one-loop corrections are suppressed by a factor 1/N; here it is shown that the two-loop corrections are suppressed by 1/N2. To leading order, these corrections are exactly the same as would be calculated in the constituent quark model. This method therefore offers a different approach to the constituent quark.

Download or read book Quarks Baryons and Chiral Symmetry written by Atsushi Hosaka and published by World Scientific. This book was released on 2001 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes baryon models constructed from quarks, mesons and chiral symmetry. The role of chiral symmetry and of quark model structure with SU(6) spin-flavor symmetry are discussed in detail, starting from a pedagogic introduction. Emphasis is placed on symmetry aspects of the theories. As an application, the chiral bag model is studied for nucleon structure, where important methods of theoretical physics, mostly related to the semiclassical approach for a system of strong interactions, are demonstrated. The text is more practical than formal; tools and ideas are explained in detail while solving actual problems. By checking each step of the computations, readers can learn not only the calculational techniques but also the essential ideas behind them.
Download or read book The Quark Structure of Hadrons written by Claude Amsler and published by Springer. This book was released on 2018-10-30 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Novel forms of matter, such as states made of gluons (glueballs), multiquark mesons or baryons and hybrid mesons are predicted by low energy QCD, for which several candidates have recently been identified. Searching for such exotic states of matter and studying their production and decay properties in detail has become a flourishing field at the experimental facilities now available or being built - e.g. BESIII in Beijing, BELLE II at SuperKEKB, GlueX at Jefferson Lab, PANDA at FAIR, J-PARC and in the upgraded LHC experiments, in particular LHCb. A modern primer in the field is required so as to both revive and update the teaching of a new generation of researchers in the field of QCD. These lectures on hadron spectroscopy are intended for Master and PhD students and have been originally developed for a course delivered at the Stefan Meyer Institute of the Austrian Academy of Sciences. They are phenomenologically oriented and intended as complementary material for basic courses in particle and nuclear physics. The book describes the spectra of light and heavy mesons and baryons, and introduces the fundamental properties based on symmetries. Further, it derives multiplet structures, mixing angle, decay coupling constants, magnetic moments of baryons, and predictions for multiquark states and compares these with suitable experimental data. Basic methods of calculating decay angular distributions and determining masses and widths of resonances are also presented. The appendices provide students and newcomers to the field with the necessary background information, and include a set of problems and solutions.
Download or read book Quarks Bound by Chiral Fields written by Georges Ripka and published by Oxford University Press. This book was released on 1997 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Murray Gell mann Selected Papers written by Harald Fritzsch and published by World Scientific. This book was released on 2010-02-08 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: Murray Gell-Mann is one of the leading physicists of the world. He was awarded the Nobel Prize in Physics in 1969 for his work on the classification and symmetries of elementary particles, including the approximate SU(3) symmetry of hadrons. His list of publications is impressive; a number of his papers have become landmarks in physics. In 1953, Gell-Mann introduced the strangeness quantum number, conserved by the strong and electromagnetic interactions but not by the weak interaction. In 1954 he and F E Low proposed what was later called the renormalization group. In 1958 he and R P Feynman wrote an important article on the V-A theory of the weak interaction. In 1961 and 1962 he described his ideas about the SU(3) symmetry of hadrons and its violation, leading to the prediction of the Ω- particle. In 1964 he proposed the quark picture of hadrons. In 1971 he and H Fritzsch proposed the exactly conserved “color” quantum number and in 1972 they discussed what they later called quantum chromodynamics (QCD), the gauge theory of color. These major publications and many others are collected in this volume, providing physicists with easy access to much of Gell-Mann's work. Some of the articles are concerned with his recollections of the history of elementary particle physics in the third quarter of the twentieth century.
Download or read book Currents and Mesons written by J. J. Sakurai and published by University of Chicago Press. This book was released on 1969-01-15 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: A Tour of the Subatomic Zoo is a brief and ambitious expedition into the remarkably simple ingredients of all the wonders of nature. Tour guide, Professor Cindy Schwarz clearly explains the language and substance of elementary particle physics for the 99% of us who are not physicists. With hardly a mathematical formula, views of matter from the atom to the quark are discussed in a form that an interested person with no physics background can easily understand. It is a look not only into some of the most profound insights of our time, but a look at the answers we are still searching for. College and university courses can be developed around this book and it can be used alone or in conjunction with other material. Even college physics majors would enjoy reading this book as an introduction to particle physics. High-school, and even middle-school, teachers could also use this book to introduce this material to their students. It will also be beneficial for high-school teachers who have not been formally exposed to high-energy physics, have forgotten what they once knew, or are no longer up to date with recent developments.
