Strong Interactions in Spacelike and Timelike Domains: Dispersive Approach provides the theoretical basis for the description of the strong interactions in the spacelike and timelike domains. The book primarily focuses on the hadronic vacuum polarization function, R-ratio of electron-positron annihilation into hadrons, and the Adler function, which govern a variety of the strong interaction processes at various energy scales. Specifically, the book presents the essentials of the dispersion relations for these functions, recaps their perturbative calculation, and delineates the dispersively improved perturbation theory. The book also elucidates the peculiarities of the continuation of the spacelike perturbative results into the timelike domain, which is indispensable for the studies of electron-positron annihilation into hadrons and the related processes.
Heavy Flavors covers the proceedings of the Third Topical Seminar on Heavy Flavors, held in San Miniato, Italy on June 17-21, 1991. The book focuses on the reactions, properties, characteristics, and transformations of heavy flavors. The publication first offers information on flavor factories and monochromatization as the way to maximum luminosity B-factories, as well as design strategies and parameters, requirements, luminosity limitations, and B-factory with monochromatization and vertical separation. The book then ponders on theoretical results in heavy quark hadroproduction; heavy flavor production at high energies; and leptonic decay constants of heavy mesons. The book examines heavy baryon transitions and the heavy quark effective theory; non universality of nucleon sea distributions probed by neutrinos and muons; and heavy flavor physics at hadron colliders. The publication is a dependable reference for readers interested in the study of heavy flavors.
Mathematics Research Center Symposium: Theory of Dispersed Multiphase Flow covers the proceedings of an advanced seminar conducted by the Mathematics Research Center of the University of Wisconsin-Madison on May 26-28, 1982. The book focuses on solutions of long chain polymers in liquids, magnetic control of particle suspensions in fluid streams, aerosols, dense granular flows, and ice crystals or vapor bubbles dispersed in river waters. The selection first elaborates on the effects of interactions between particles on the rheology of dispersions; rheology of concentrated macromolecular solutions; and a survey of results in the mathematical theory of fluidization. Discussions focus on Rayleigh-Taylor instabilities, linear instability theory, steady solutions, general theory for polymer solutions and suspensions, electrostatically concentrated suspensions, and pair interaction theories. The text then examines instability in settling of suspensions due to Brownian effects; enhanced sedimentation in vessels having inclined walls; and simple kinetic theory of Brownian diffusion in vapors and aerosols. The text takes a look at the simulation of aerosol dynamics, continuum modeling of two-phase flows, multiphase mixture theory for fluid-particle flows, and mixture theory for turbulent diffusion of heavy particles. Topics include plane gravity flow, decomposition and averaging, isothermal flows of dilute suspensions, kinematics and the equations of motion, diffusional regularization, kinematic waves, and aerosol formation and growth in uniform systems. The selection is a valuable source of data for researchers interested in the theory of dispersed multiphase flow.
Quantum and Classical Connections in Modeling Atomic, Molecular and Electrodynamic Systems is intended for scientists and graduate students interested in the foundations of quantum mechanics and applied scientists interested in accurate atomic and molecular models. This is a reference to those working in the new field of relativistic optics, in topics related to relativistic interactions between very intense laser beams and particles, and is based on 30 years of research. The novelty of this work consists of accurate connections between the properties of quantum equations and corresponding classical equations used to calculate the energetic values and the symmetry properties of atomic, molecular and electrodynamical systems, as well as offering applications using methods for calculating the symmetry properties and the energetic values of systems and the calculation of properties of high harmonics in interactions between very intense electromagnetic fields and electrons.
Few Particle Problems in the Nuclear Interaction emerged from the International Conference on Few Particle Problems in the Nuclear Interaction held in Los Angeles, from August 28-September 1, 1972. The aim of the conference was to discuss recent developments in low and medium energy few-particle problems. This included the fields of the nuclear three-body problem; nuclear forces (in particular, three-body forces); symmetries; and the interaction of mesons, leptons, and photons with few-nucleon systems. Special sessions were also devoted to the application of the results and techniques of the few-particle research to the problems of other fields, in particular nuclear structure and astrophysics. The conference was organized into nine plenary sessions and 13 parallel sessions. This volume contains 184 papers presented during the nine sessions on the following topics: the nucleon-nucleon interaction; three-body forces; hypernuclear systems; symmetries; three-body problems; multiparticle reactions; proposed studies of few-nucleon systems with meson factories; few-nucleon systems and leptons, mesons, and photons; and applications.
Hadrons and Their Interactions: Current and Field Algebra, Soft Pions, Supermultiplets, and Related Topics focuses on formulas, principles, and interactions involved in the study of physics. The compilation contains the papers presented at the ""Ettore Majorana,"" held in Erice on July 1-14, 1967. Divided into three parts with 22 chapters, the compilation focuses first on lectures on soft pions; the method of phenomenological lagrangians and algebra of fields; and radiative corrections to beta decay and the structure of hadrons. The second part focuses on seminars. The areas covered include a review of coherent production in strong interactions; spontaneous breakdown and the weak interaction angle; and the symmetries of the S-matrix. The concluding part also focuses on lectures, including lectures on the present status of the fundamental interactions; a pedagogical exercise in binning and resolution; and the pomeranchuk affair and twisting trajectories. The compilation is a valuable source of data for readers and physicists wanting to explore the interactions of hadrons.
This book provides a philosophically informed and mathematically rigorous introduction to the 'standard model' of particle physics. The standard model is the currently accepted and experimentally verified model of all the particles and interactions in our universe. All the elementary particles in our universe, and all the non-gravitational interactions -the strong nuclear force, the weak nuclear force, and the electromagnetic force - are collected together and, in the case of the weak and electromagnetic forces, unified in the standard model. Rather than presenting the calculational recipes favored in most treatments of the standard model, this text focuses upon the elegant mathematical structures and the foundational concepts of the standard model.
The Standard Model of elementary particles and interactions is one of the best tested theories in physics. It has been found to be in remarkable agreement with experiment, and its validity at the quantum level has been successfully probed in the electroweak sector. In spite of its experimental successes, though, the Standard Model suffers from a number of limitations, and is likely to be an incomplete theory. It contains many arbitrary parameters; it does not include gravity, the fourth elementary interaction; it does not provide an explanation for the hierarchy between the scale of electroweak interactions and the Planck scale, characteristic of gravitational interactions; and finally, it fails to account for the dark matter and the baryon asymmetry of the universe. This led particle theorists to develop and study various extensions of the Standard Model, such as supersymmetric theories, Grand Unified Theories or theories with extra space-time dimensions - most of which have been proposed well before the experimental verification of the Standard Model. The coming generation of experimental facilities (such as high-energy colliders, B-physics experiments, neutrino superbeams, as well as astrophysical and cosmological observational facilities) will allow us to test the predictions of these theories and to deepen our understanding of the fundamental laws of nature.This book is a collection of lectures given in August 2005 at the Les Houches Summer School on Particle Physics beyond the Standard Model. It provides a pedagogical introduction to the various aspects of particle physics beyond the Standard Model, covering each topic from the basics to the most recent developments: supersymmetric theories, Grand Unified Theories, theories with extra dimensions, flavour physics and CP violation, neutrino physics, astroparticle physics and cosmology.
The purpose of this volume is to trace the development of the theoretical understanding of quark-gluon plasma, both in terms of theequation of state and thermal correlation functions and in terms ofits manifestation in high energy nuclear collisions. Who among us hasnot wondered how tall a mountain is on a neutron star, what happenswhen matter is heated and compressed to higher and higher densities,what happens when an object falls into a black hole, or what happenedeons ago in the early universe? The study of quark-gluon plasma is related in one way or another to these and other thought provoking questions. Oftentimes the most eloquent exposition is given in theoriginal papers. To this end a selection is made of what are themost important pioneering papers in this field. The early 1950s wasan era when high energy multiparticle production in cosmic rayinteractions attracted the attention of some of the brightest minds in physics, and so it should be no surprise that the first reprinted papers deal with the introduction of statistical models of particleproduction. The quark model arose in the 1960s, while QCD as suchwas recognized as the theory of the strong interactions in the1970's. The behavior of matter at high temperatures and supranucleardensities became of wide interest in the nuclear and particle physicscommunities starting in the 1970s, which is when the concept ofquark-gluon plasma became established. The history of the field hasbeen traced up to the early 1990s. There are three reasons forstopping at that point in time. First, most of the key theoreticalconcepts and formalisms arose before 1993, although many of themcontinue to be developed today and hopefully well into the future. Second, papers written after 1992 are much more readily availablethan those writen before due to the advent of the World Wide Web andits electronic preprint databases and journals. Finally, in makingthis collection of reprints available as hardcopy one is limited inthe number of pages, and some papers in the present selection shouldhave been deleted in order to make room for post-1993 papers. For thesame reason the subject focus must of necessity be limited, whichmeans that in this reprint collection two wide subject areas are not addressed: the behavior of nuclear matter under extreme conditionsis not reported, nor is quark matter in neutron stars. The broadcategories into which the material has been placed, reflect thediverse studies of quark-gluon plasma and its manifestation. They are: phase-space models of particle production, perturbative QCDplasma, lattice gauge theory, fluid dynamics and flow, strangeness, heavy flavor (charm), electromagnetic signals, parton cascade andminijets, parton energy loss and jet quenching, Hanbury Brown--Twiss(HBT) interferometry, disoriented chiral condensates, phasetransition dynamics and cosmology, and color superconductivity. Eachchapter is prefaced by an introduction, which contains a list ofsignificant papers which is more complete than the reprinted papers,though by no means exhaustive. It also contains citations to mostrelevant papers published up to the date of completion of this volume(fall 2002). It is hoped that the short reviews will help bring thereader up to date on the latest developments. The selection ofpapers cited in each chapter, and in particular the ones selected forreprinting, is solely the responsibility of the Editors. It is basedon their best judgement and experience in this field dating back tothe mid-1970s. In order to be reprinted a paper must have beenpioneering in the sense of originality and impact on the field.Generally they have been cited over a hundred times by other paperspublished in refereed journals. The final selection was reviewed anddiscussed among the Editors repeatedly. Just because a paper is not included does not mean they do not know of it or do not have a highregard for it. All of the papers cited or reprinted are originalresearch contributions. There are three other types of publicationslisted. The first is a compilation of books. The second is a listof reviews, many of which contain a significant amount of original material. The third is a list of the proceedings of the series ofQuark Matter meetings, the primary series of internationalconferences in this field that is attended by both theorists andexperimentalists.
In recent years, the main research areas were photonuclear reactions and meson productions by using the first high-duty tagged photon beam and the TAGX spectrometer. Although this field is developing quite rapidly, the synchrotron was closed in 1999 after 37 years of operation, and these activities continue at new facilities. It was therfore a good time to discuss the present status and future directions of this field at this occasion. The Symposium was attended by 85 physicists and 35 talks were presented. This book contains the papers presented in the scientific program of the Symposium. aspects of kaon photoproduc
