Phenomenology And Lattice Qcd - Proceedings Of The 1993 Uehling Summer School by Sharpe Stephen R Pdf
These six lecture courses provide the background necessary in the understanding of the application of lattice methods to phenomenology, and give examples of interesting applications. The first three introduce the necessary techniques: chiral perturbation theory, heavy quark effective field theory, and lattice gauge theory. The remaining three describe how these techniques are used, mainly in lattice simulations, in the study of interesting phenomenological questions: vacuum structure, finite temperature QCD, and electroweak matrix elements. What distinguishes this volume from others is its focus on providing the background necessary for us to understand the methods and the significance of lattice gauge theory research.
Phenomenology of Large Nc QCD by Richard F. Lebed Pdf
The generalization of QCD from three to C colors, developed in 1974 by Nobel laureate Gerard 't Hooft, has proved to be an extraordinarily useful and robust theoretical extension for studying the behavior of strong interaction physics. This book is the proceedings of the first-ever meeting exclusively devoted to large NC QCD. The workshop brought together representatives of many subdisciplines for a meeting of minds on topics ranging from finite temperature and density to the lattice, perturbative QCD, instantons, mesons, baryons, and nuclear physics. Beginning with 't Hooft's keynote presentation, the contributions are designed to introduce uses of large NC methods in each specialty to a broader particle physics audience."
N* Physics - Proceedings Of The Fourth Cebaf/int Workshop by Harry Tsung-shung Lee,Winston Roberts Pdf
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 → N∗ 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.
Nuclear Physics With Effective Field Theory - Proceedings Of The Joint Caltech/int Workshop by Ubirajara Van Kolck,Ryoichi Seki,Martin J Savage Pdf
Effective field theory (EFT), a technique used extensively in particle physics, provides a framework for systematically describing nuclear systems in a way consistent with quantum chromodynamics, the underlying theory of strong interactions. Because it offers the possibility of a unified description of all low-energy processes involving nucleons, it has the potential to become the foundation of conventional nuclear physics.Since the early 1990's when Weinberg applied the techniques of EFT to multiple-nucleon systems, significant developments have been made. However, serious obstacles have also been encountered. This book contains the proceedings of the Workshop on Nuclear Physics with Effective Field Theory, held in the Kellogg Radiation Laboratory at Caltech on the 26th and 27th of February 1998, which specifically addressed those issues. Physicists from different areas of sub-atomic physics gathered in an attempt to arrive at a consistent power counting scheme for the nucleon-nucleon interaction, a first step toward dealing with few-nucleon systems and ultimately nuclear matter and finite nuclei.
Opportunities With Exotic Beams - Proceedings Of The Third Anl/msu/jina/int Ria Workshop by Thomas Duguet,Henning Esbensen,Kenneth M Nollett,Craig D Roberts Pdf
This volume explores, explains, and supports the case for an advanced exotic beam facility from a theoretical perspective. The US nuclear physics community and the US Department of Energy are committed to building such a facility. The topics covered constitute a survey of present activities in nuclear theory that will set the challenges for an advanced exotic-beam facility and provide the starting point for interpreting experiments that will be conducted there. The research programs described are all at the forefront of nuclear theory, and they include research on the detailed structures of the lightest nuclei, systematic descriptions of all observed nuclei, nuclear tests of fundamental symmetries of nature, the explosion mechanisms of supernovae, and astrophysical synthesis of the heavy elements, as well as several other topics.
The r-process is a major mechanism for producing elements heavier than Fe. In this book, a summary of recent developments in theoretical, experimental and observational studies of the r-process are presented in 25 contributions. The collected papers are up to date, comprehensive and yet concise. The topics covered include experiments on nuclei far from stability, nuclear theory input for the r-process, observational and theoretical studies on abundances of heavy nuclei, and astrophysical models of the r-process.The proceedings have been selected for coverage in: ?

Quark Confinement And The Hadron Spectrum Iii, Jun 98, Usa by Nathan Isgur Pdf
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.

Open Issues in Core Collapse Supernova Theory by Anthony Mezzacappa,George M Fuller Pdf
Efforts to uncover the explosion mechanism of core collapse supernovae and to understand all of their associated phenomena have been ongoing for nearly four decades. Despite this, our theoretical understanding of these cosmic events remains limited; two- and three-dimensional modeling of these events is in its infancy. Most of the modeling efforts over the past four decades have, by necessity, been constrained to spherical symmetry, with the first two-dimensional, albeit simplified, models appearing only during the last decade. Simulations to understand the complex interplay between the turbulent stellar core fluid flow, its magnetic fields, the neutrinos produced in and emanating from the proto-neutron star, the stellar core rotation, and the strong gravitational fields have yet to be performed. Only subsets of these fundamental ingredients have been included in the models thus far, often with approximation. The purpose of this volume is to identify the outstanding issues that remain in order to come to a complete understanding of these important astrophysical events. As the book focuses on open issues rather than the current state of the art in the field — although the latter will certainly be discussed — it will remain relevant for some time.

Exclusive & Semi-exclusive Processes At High Momentum Transfer by Carl Carlson,Anatoly Radyushkin Pdf
This book constitutes the proceedings of a workshop on 'Exclusive and Semi-exclusive Processes at High Momentum Transfer', sponsored by the Institute for Nuclear Theory (Seattle) and the Thomas Jefferson National Accelerator Facility (Jefferson Laboratory). The workshop was inspired by recent progress in the field, particularly in the uses of off-forward or skewed parton distributions to elucidate nucleon structure. This book contains the written versions of 41 scientific talks, on subjects including the aforementioned skewed parton distributions, and also on deeply virtual Compton scattering, semi-exclusive (or semi-inclusive) reactions, and hard elastic and transition form factors.
Nuclear Physics With Effective Field Theory Ii by Paulo F Bedaque,Ubirajara Van Kolck,Martin J Savage,Ryoichi Seki Pdf
The method of effective field theory (EFT) is ideally suited to deal with physical systems containing separate energy scales. Applied to low energy hadronic phenomena it provides a framework for systematically describing nuclear systems in a way consistent with quantum chromodynamics, the underlying theory of strong interactions. Because EFT offers the possibility of a unified description of all low energy processes involving nucleons, it has the potential to become the foundation of conventional nuclear physics.Much progress has been made recently in this field: a number of observables in the two-nucleon sector were computed and compared to experiment, issues related to the extension of the EFT program to the three-nucleon sector were clarified, and the convergence of the low energy expansion was critically examined. This book contains the proceedings of the Workshop on 'Nuclear Physics with Effective Field Theory II', where these and other developments were discussed.
