This book provides insight into concept of the weak interaction and its integration into the conceptual structure of elementary particle physics. It exhibits the important role of the weak interaction in nuclear, particle and astrophysics together with the close connection between these areas.
The Weak Interaction in Nuclear, Particle and Astrophysics presents concepts of the weak interaction and its integration into modern gauge theories of particle physics, such as grand unification and supersymmetry. The book explores the close connections between micro (nuclear and particle) physics and macro physics (astrophysics and cosmology) induced by the weak interaction. Special attention is given to neutrinos, which have a key role in the understanding of elementary particle theories. In addition to the theoretical aspects, the book covers the important research topics of solar and galactic neutrinos and double beta decay.
Recently a symbiotic relationship between particle and nuclear physics has developed, with techniques and ideas from one field fertilizing developments in the other. This work outlines concepts from modern particle physics important to the current understanding of nuclear physics and reviews experiments involving nuclei which have influenced the present particle physics view of the weak interaction. In his discussion, the author summarizes both past and present activity in the field and identifies areas for future work. Familiarity with quantum mechanics is assumed in the presentation of ideas in this book intended for readers at the graduate level and beyond. A major goal of Weak Interactions in Nuclei is to encourage further activity at the intersection of particle and nuclear physics, two path-breaking areas of study in modern physics.

Nuclear physics is presently experiencing a thrust towards fundamental phy sics questions. Low-energy experiments help in testing beyond today's stan dard models of particle physics. The search for finite neutrino masses and neutrino oscillations, for proton decay, rare and forbidden muon and pion de cays, for an electric dipole moment of the neutron denote some of the efforts to test today's theories of grand unification (GUTs, SUSYs, Superstrings, ... ) complementary to the search for new particles and symmetries in high-energy experiments. The close connections between the laws of microphysics, astrophysics and cosmology open further perspectives. This concerns, to mention some of them, properties of exotic nuclei and nuclear matter, and star evolution; the neutrino and the dark matter in the universe; relations between grand unification and evolution of the early universe. The International Symposium on Weak and Electromagnetic Interactions in Nuclei (W.E.LN. 1986)' held in Heidelberg 1-5 July 1986, in conjunction with the 600th anniversary of the University of Heidelberg, brought together experts in the fields of nuclear and particle physics, astrophysics and cosmol ogy.
In recent years, the study of weak interaction and its relationship with the other fundamnetal interactions of nature has progressed rapidly. Weak interactions of leptons and quarks provides an up-to-date account of this continuing research. The Introduction discusses early models and historical developments in the understanding of the weak force. The authors then give a clear presentation of the modern theoretical basis of weak interactions, going on to discuss recent advances in the field. These include development of the eletroweak gauge theory, and the discovery of neutral currents and of a host of new particles. There is also a chapter devoted entirely to neutrino astrophysics. Its straightforward style and its emphasis on experimental results will make this book an excellent source for students (problem sets are included at the end of each chapter) and experimentalists in the field. Physicists whose speciality lies outside the study of elementary particle physics will also find it useful.
Nuclear astrophysics as it stands today is a fascinating science. Even though, compared to other scientific fields, it is a young discipline which has developed only in this century, it has answered many questions concerning the under standing of our cosmos. One of these great achievements was the concept of nucleosynthesis, the creation of the elements in the early universe in interstellar matter and in stars. Nuclear astrophysics has continued, to solve many riddles of the evolution of the myriads of stars in our cosmos. This review volume attempts to provide an overview of the current status of nuclear astrophysics. Special emphasis is given to the interdisciplinary nature of the field: astronomy, nuclear physics, astrophysics and particle physics are equally involved. One basic effort of nuclear astrophysics is the collection of ob servational facts with astronomical methods. Laboratory studies of the nuclear processes involved in various astrophysical scenarios have provided fundamen tal information serving both as input for and test of astrophysical models. The theoretical understanding of nuclear reaction mechanisms is necessary, for example, to extrapolate the experimentally determined reaction rates to the thermonuclear energy range, which is relevant for the nuclear processes in our cosmos. Astrophysical models and calculations allow us to simulate how nuclear processes contribute to driving the evolution of stars, interstellar matter and the whole universe. Finally, elementary particle physics also plays an important role in the field of nuclear astrophysics, for instance through weak interaction processes involving neutrinos.
This book is intended for undergraduate or beginning graduate students. The net outcome is material to cover one integrated course on Nuclear and Particle Physics as well as Astrophysics.There are many advantages in teaching all these subjects together as they have become increasingly inseparable. From a theoretical point of view, understanding the similarities between atoms, nuclei and other hadrons and applying analogs from one to the other have been very effective in research and they have led to the development of all these fields. From an experimental point of view, a high energy experimentalist must understand nuclear physics, if he or she wants to construct new devices, like detectors, etc., appropriate for observing new high energy phenomena. Furthermore, an understanding of certain areas of astrophysics and the physics of the cosmos, demands a good grasp of both nuclear and particle physics.This book is intended as a menu from which the reader can pick material according to his or her taste and interests. The authors inserted proper cross references to make a specific selection by the reader from this menu as easily digestible as possible. The authors supplied sets of problems with varying degree of complexity, accompanied by hints or a sketch of the solution, if needed, in most chapters.
Covers all the phenomenological and experimental data on nuclear physics and demonstrates the latest experimental developments that can be obtained. Introduces modern theories of fundamental processes, in particular the electroweak standard model, without using the sophisticated underlying quantum field theoretical tools. Incorporates all major present applications of nuclear physics at a level that is both understandable by a majority of physicists and scientists of many other fields, and usefull as a first introduction for students who intend to pursue in the domain.
The new results on the neutrino oscillations belong to the highlights of the particle and nuclear physics in the last few years. We tried to include these new developments in the present edition. Furthermore, we included a new section on the double beta decay. Of special interest is the possible neutrino less double beta decay. Its existence would require a non-trivial extension of the standard model of elementary particles. We have much appreciated the discussion and support of Gerry Garvey (Los Alamos) during the preparation of the revised version of the chapter on neu trino oscillations and the new chapter on double beta decay. We would like to thank Kunio Inoue (Sendai) for informing us about the newest results on neutrino mixing. We would like to thank Claudia Ries (Heidelberg) for carefully reading the manuscript and Jiirgen Sawinski (Heidelberg) for the excellent work he has done in formatting the book.
