Available in PDF, EPUB and Kindle. Book excerpt: Chiral effective field theory is a powerful tool in dealing with nuclear forces in both a systematic and model-independent way. In the recent past, two-, three-, and four-nucleon forces up to next-to-next-to-next-to-leading order (N3 LO) have been derived and and applied fairly successfully in nuclear few- and many-body systems. However, an important issue has been neglected in all of this work: Non-perturbative renormalization, which is crucial to prove the model-independence of the theory. In this thesis, I have have investigated systematically the renormalization of chiral neutron-proton (np) potentials at order NLO and NNLO applying Weinberg counting for the counter terms (NN contact terms). I show that the reproduction of the np data at these energies is generally poor at NLO, while at NNLO the [chi] 2 /datum assumes acceptable values (a clear demonstration of order-by-order improvement). Moreover, at NNLO one observes "plateaus" of constant low [chi]2 for cutoff parameters ranging from 450 to 850 MeV. This may be perceived as cutoff independence (and, thus, successful renormalization) in the relevant range of cutoff parameters. Preliminary results for N3 LO will also be discussed.

This book was released on 2007 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis work has investigated the Renormalization Group theory for the nucleon-nucleon interaction. Conventional nuclear many-body calculations have the following sources of non-perturbative physics: (1) a strongly repulsive short-range interaction, (2) a tensor force, e.g. from pion exchange, which is highly singular at short-distances, (3) the presence of low-energy bound states or nearly bound states (in the S waves).

This book was released on 1998-09-28 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2014-10-03 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: This proceedings volume collected papers presented at a recent symposium on Chiral Symmetry in Hadrons and Nuclei — the seventh in a series of international symposia — with an aim of providing a platform for discussions among the experts and an overview of the present status in the hadron and nuclear physics related to the chiral symmetry.The recent past years have seen a remarkable progress towards a unified description of nonperturbative strong interaction phenomena based on the fundamental theory of the strong interaction, Quantum ChromoDynamics, and Effective Field Theories. The topics discussed in these proceedings include: chiral and heavy-quark spin symmetry; chiral dynamics of few-body hadron systems; chiral symmetry and hadrons in a nuclear medium; chiral dynamics in nucleon-nucleon interaction and atomic nuclei; chiral symmetry in rotating nuclei; hadron structure and interactions; exotic hadrons, heavy flavor hadrons and nuclei; mesonic atoms and nuclei.

Download or read book The Nucleon nucleon Interaction and the Nuclear Many body Problem written by Gerald E. Brown and published by World Scientific. This book was released on 2010 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of some key developments in the understanding of the nucleon-nucleon interaction and nuclear many-body theory. The main problems at the level of meson exchange physics have been solved, and we have an effective field theory using a phenomenological interaction pioneered by Achim Schwenk and Scott Bogner, which is nearly universally accepted as a unique low-momentum interaction that includes all experimental data to date.This understanding is based on a multi-step development in which different scientific insights and a wide range of physical and mathematical methodologies fed into each other. It is best appreciated by looking at the different 'steps along the way', starting with the pioneering work of Brueckner and his collaborators that was just as necessary and important as the insightful masterly improvements to Brueckner's theory by Hans Bethe and his students. Moving on from there, the off-shell effects that bedeviled Bethe's work — which had resulted in the 1963 Reference Spectrum Method — were treated relatively accurately by introducing an energy gap between initial bound states and an intermediate state. With their influential 1967 paper, Brown and Kuo prepared the effective field theory. Later, the introduction of 'Brown-Rho scaling' deepened understanding of saturation in the many-body system and fed directly into recent work on carbon-14 dating.

This book was released on 2010-07-05 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of some key developments in the understanding of the nucleon-nucleon interaction and nuclear many-body theory. The main problems at the level of meson exchange physics have largely been solved, and we now have an effective nucleon-nucleon interaction, pioneered in a renormalization group formalism by several of us at Stony Brook and our colleagues at Naples, which is nearly universally accepted as the unique low-momentum interaction that includes all experimental information to date.Our present understanding of these issues is based on a multi-step development in which different scientific insights and a wide range of physical and mathematical methodologies fed into each other. It is best appreciated by looking at the ‘steps along the way’, starting with the pioneering work of Brueckner and his collaborators that was just as necessary and important as the insightful improvements to Brueckner's theory by Hans Bethe and his students. Moving on from there, microscopic methods for nuclear structure calculations using the Brueckner G-matrix, and later low-momentum nucleon interactions, were developed and applied. With their influential 1967 paper, Brown and Kuo prepared the effective theory that allowed the description of nuclear properties directly from the underlying nucleon-nucleon interaction. Later, the addition of ‘Brown-Rho scaling’ to the one-boson-exchange model deepened the understanding of nuclear matter saturation, carbon-14 dating and the structure of neutron stars.

This book was released on 2012-12-06 with total page 722 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the Proceedings of the "XXIV. Inter nationale Universitatswochen fur Kernphysik" held in Schlad ming, Austria, in February 1985. It consists of the written versions of the lectures (3-4 hours) given at this winter school and includes also most of the seminars (30-50 minutes) presented. In choosing the topic for the 1985 meeting, our aim was to give an account of the present understanding of the nucleon-nucleon as well as nucleon-antinucleon inter actions. This field, which is of definite relevance in nuclear and particle physics, has witnessed a rapid develop ment in recent times both in theory and experiment. New evidence has emerged in the whole range from low to extremely high energies. It was an exciting experience to bring to gether knowledge from the very domains of nuclear and high energy physics as well as to meet the respective researchers. Thanks to the efforts of the lecturers, who did a splendid job in presenting the lectures and in preparing their lecture notes, a comprehensive insight into the hadronic interaction between nucleons and anti-nucleons was achieved. The lecture notes were reconsidered by the authors after the meeting and are now being published in their final form. The seminars mainly dealt with specific topics currently under investiga tion within this rather wide field. We are grateful to all authors for their efforts, as they made it possible to speed up the publication of these proceedings.
Download or read book Handbook of Nuclear Physics written by Isao Tanihata and published by Springer Nature. This book was released on 2023-09-04 with total page 4180 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook is a comprehensive, systematic source of modern nuclear physics. It aims to summarize experimental and theoretical discoveries and an understanding of unstable nuclei and their exotic structures, which were opened up by the development of radioactive ion (RI) beam in the late 1980s. The handbook comprises three major parts. In the first part, the experiments and measured facts are well organized and reviewed. The second part summarizes recognized theories to explain the experimental facts introduced in the first part. Reflecting recent synergistic progress involving both experiment and theory, the chapters both parts are mutually related. The last part focuses on cosmo-nuclear physics—one of the mainstream subjects in modern nuclear physics. Those comprehensive topics are presented concisely. Supported by introductory reviews, all chapters are designed to present their topics in a manner accessible to readers at the graduate level. The book therefore serves as a valuable source for beginners as well, helping them to learn modern nuclear physics.

This book was released on 2020-04-20 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: The topic of the CVIII session of the Ecole de Physique des Houches, held in July 2017, was Effective Field Theory in Particle Physics and Cosmology. Effective Field Theory (EFT) is a general method for describing quantum systems with multiple length scales in a tractable fashion. It allows to perform precise calculations in established models (such as the Standard Models of particle physics and cosmology), as well as to concisely parametrise possible effects from physics beyond the Standard Models. The goal of this school was to offer a broad introduction to the foundations and modern applications of Effective Field Theory in many of its incarnations. This is all the more important as there are preciously few textbooks covering the subject, none of them in a complete way. In this book, the lecturers present the concepts in a pedagogical way so that readers can adapt some of the latest developments to their own problems. The chapters cover almost all the lectures given at the school and will serve as an introduction to the topic and as a reference manual to students and researchers.
