Available in PDF, EPUB and Kindle. Book excerpt: This volume comprises a collection of invited papers presented at the interna tional symposium "The Future of Muon Physics", May 7-9 1991, at the Ruprecht Karls-Universitat in Heidelberg. In the inspiring atmosphere of the Internationales Wissenschaftsforum researchers working worldwide at universities and at many inter national accelerator centers came together to review the present status of the field and to discuss the future directions in muon physics. The muon, charged lepton of the second generation, was first oberved some sixty years ago~ Despite many efforts since, the reason for its existence still remains a secret to the scientific community challenging both theorists and experimentalists. In modern physics the muon plays a key role in many topics of research. Atomic physics with negative muons provides excellent tests of the theory of quantum electrodynamics and of the electro-weak interaction and probes nuclear properties. The. purely leptonic hydrogen-like muonium atom allows tests of fun damental laws in physics and the determination of precise values for fundamental constants. New measurements of the anomalous magnetic moment of the muon will probe the renormalizability of the weak interaction and will be sensitive to physics beyond the standard model. The muon decay is the most carefully studied weak process. Searches for rare decay modes of muons and for the conversion of muonium to antimuonium examine the lepton number conservation laws and new speculative theories. Nuclear muon capture addresses fundamental questions like tests of the CPT theorem.

Book excerpt: A new measurement of the anomalous magnetic moment of the muon, $a_{\mu} \equiv (g-2)/2$, will be performed at the Fermi National Accelerator Laboratory with data taking beginning in 2017. The most recent measurement, performed at Brookhaven National Laboratory and completed in 2001, shows a 3.5 standard deviation discrepancy with the standard model prediction of $a_\mu$. The new measurement will accumulate 21 times those statistics using upgraded detection and storage ring systems, enabling a measurement of $a_\mu$ to 140 ppb, a factor of 4 improvement in the uncertainty the previous measurement. This improvement in precision, combined with recent and ongoing improvements in the evaluation of the QCD contributions to the $a_\mu$, could provide a 7.5$\sigma$ discrepancy from the standard model if the current difference between experiment and theory is confirmed, a possible indication of new physics.

This book was released on 2021-04-20 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vladimir Naumovich Gribov is one of the creators of modern theoretical physics. The concepts and methods that Gribov has developed in the second half of the 20th century became cornerstones of the physics of high energy hadron interactions (relativistic theory of complex angular momenta, a notion of the vacuum pole — Pomeron, effective reggeon field theory), condensed matter physics (critical phenomena), neutrino oscillations, and nuclear physics.His unmatched insights into the nature of the quantum field theory helped to elucidate, in particular, the origin of classical solutions (instantons), quantum anomalies, specific problems in quantization of non-Abelian fields (Gribov anomalies, Gribov horizon), and the role of light quarks in the color confinement phenomenon.The Memorial Workshop devoted to Gribov's 90th birthday was cancelled due to the coronavirus pandemic in 2020; however, this did not deter the collection of many new studies in challenging theoretical physics problems across a broad variety of topics, and shared memories about their colleague, great teacher and friend. The contributions of this memorial volume affirms the everlasting impact of Gribov's scientific heritage upon the physics of the 21st century.
Download or read book The Hydrogen Atom written by S.G. Karshenboim and published by Springer. This book was released on 2007-12-03 with total page 778 pages. Available in PDF, EPUB and Kindle. Book excerpt: For more than a century, studies of atomic hydrogen have been a rich source of scientific discoveries. These began with the Balmer series in 1885 and the early quantum theories of the atom, and later included the development of QED and the first successful gauge field theory. Today, hydrogen and its relatives continue to provide new fundamental information, as witnessed by the contributions to this book. The printed volume contains invited reviews on the spectroscopy of hydrogen, muonium, positronium, few-electron ions and exotic atoms, together with related topics such as frequency metrology and the determination of fundamental constants. The accompanying CD contains, in addition to these reviews, a further 40 contributed papers also presented at the conference "Hydrogen Atom 2" held in summer 2000. Finally, to facilitate a historical comparison, the CD also contains the proceedings of the first "Hydrogen Atom" conference of 1988. The book includes a foreword by Norman F. Ramsey.
Download or read book Muon g 2 Technical Design Report written by and published by . This book was released on 2015 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Muon (g-2) Experiment, E989 at Fermilab, will measure the muon anomalous magnetic moment a factor-of-four more precisely than was done in E821 at the Brookhaven National Laboratory AGS. The E821 result appears to be greater than the Standard-Model prediction by more than three standard deviations. When combined with expected improvement in the Standard-Model hadronic contributions, E989 should be able to determine definitively whether or not the E821 result is evidence for physics beyond the Standard Model. After a review of the physics motivation and the basic technique, which will use the muon storage ring built at BNL and now relocated to Fermilab, the design of the new experiment is presented. This document was created in partial fulfillment of the requirements necessary to obtain DOE CD-2/3 approval.

Book excerpt: Protons are accelerated to 103 GeV/c in the energy doubler/saver ring (ED/S). They are extracted, targeted, and pions are collected in the main ring at an energy of approximately 100 GeV/c. The pions decay (tau/sup .pi./sub lab/ at 100 GeV/c approximately equal to 20 .mu.s), giving birth to a muon beam. This muon beam can be extracted or bumped onto an internal target. The number of muons expected is calculated. The large aperture of the ED/S may allow a time averaged flux of as high as 107 .mu./sup +//sec to be achieved.

Book excerpt: This book provides an introduction to the current state of our knowledge about the structure of matter. Gerhard Ecker describes the development of modern physics from the beginning of the quantum age to the standard model of particle physics, the fundamental theory of interactions of the microcosm. The focus lies on the most important discoveries and developments, e.g. of quantum field theory, gauge theories and the future of particle physics. The author also emphasizes the interplay between theory and experiment, which helps us to explore the deepest mysteries of nature. "Particles, Fields, Quanta" is written for everyone who enjoys physics. It offers high school graduates and students of physics in the first semesters an encouragement to understand physics more deeply. Teachers and others interested in physics will find useful insights into the world of particle physics. For advanced students, the book can serve as a comprehensive preparation for lectures on particle physics and quantum field theory. A brief outline of the mathematical structures, an index of persons with research focuses and a glossary for quick reference of important terms such as gauge theory, spin and symmetry complete the book. From the foreword by Michael Springer: “The great successes and the many open questions this book describes illustrate how immensely complicated nature is and nevertheless how much we already understand of it.” The author Gerhard Ecker studied theoretical physics with Walter Thirring at the University of Vienna. His research focus has been on theoretical particle physics, in particular during several long-term visits at CERN, the European Organisation for Nuclear Research in Geneva. In 1986 he was promoted to Professor of Theoretical Physics at the University of Vienna. Since 1977 he has given both basic lectures in theoretical physics and advanced courses on different topics in particle physics, e.g., quantum field theory, symmetry groups in particle physics and renormalisation in quantum field theory.

This book was released on 2021-07-14 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is dedicated to Lev Okun, who passed away in November 2015. He was a true pioneer in probing fundamental dynamics.The book has two objectives. First is to showcase Okun's impact for decades since 1963, when he published his remarkable book Weak Interaction of Elementary Particles. Second is to present the current progress of our scientific community in the studies of our Universe. New directions and possible future developments are discussed, often using the past as a guide. The authors mostly focus on CP asymmetries in the transitions of hadrons and leptons, but they also discuss their rare decays, and talk about axions and supersymmetry, and possible connections with dark matter, extra dimensions, baryogenesis and multiverse.This book is suitable for readers who know quantum mechanics and quantum field theories in general.

Download or read book The Muon G 2 Experiment Overview and Status as of June 2016 written by and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Muon g-2 Experiment at Fermilab will measure the anomalous magnetic moment of the muon to a precision of 140 parts per billion, which is a factor of four improvement over the previous E821 measurement at Brookhaven. The experiment will also extend the search for the electric dipole moment (EDM) of the muon by approximately two orders of magnitude, with a sensitivity down to 10-21 e.cm. Both of these measurements are made by combining a precise measurement of the 1.45T storage ring magnetic field with an analysis of the modulation of the decay rate of higher-energy positrons (from anti-muons), recorded by 24 calorimeters and 3 straw tracking detectors. Furthermore, the recent progress in the alignment of the electrostatic quadrapole plates and the trolley rails inside the vacuum chambers, and in establishing the uniform storage ring magnetic field will be described.
