Parity Violation In Electron Scattering - Proceedings Of The Workshop

DOWNLOAD EBOOKThese proceedings cover the recent progress and future directions of parity violation in electron scattering. Both experimental and theoretical issues are discussed, such as those of hadronic structure, radiative corrections, and tests of the standard model. There are three sessions, the first of which serves as a general overview of theory and experiment. The second session deals with the technical aspects of making a measurement of the parity violating asymmetry in electron scattering, including not only detector design but polarized electron beams and beam polarimeters.. The remaining session covers the corrections to lowest order parity violating cross sections.

DOWNLOAD EBOOKIn the last few years there has been considerable progress in improving the accuracy of parity violation experiments in electron scattering at high energy and in atomic physics. Recent results are a challenge to the standard electroweak theory and our understanding of hadron structure. This book is an extensive review of the advances in this field. The theoretical framework is presented at a pedagogical level, experiments and future projects are reviewed, and the results and their interpretation are discussed in depth.

DOWNLOAD EBOOKAs a means of investigating unified gauge theories of the electro-weak interaction we have been preparing an experiment for the Bates Electron Accelerator to determine the parity violating asymmetry A = (sigma/sub R/ - sigma/sub L/) for 30° elastic scattering by 12C of 250 MeV longitudinally polarized electrons, where sigma/sub R/ and sigma/sub L/ are respectively the differential cross sections for electrons with right and left helicities. The asymmetry depends strictly on the isoscalar vector-hadronic coupling constant, and in terms of the Weinberg-Salam model is predicted to have a value of approx. 2 x 10−6 for our choice of kinematics. Central to the success of the measurement of such a small quantity is the use of an intense, highly stable source of polarized electrons. The progress in the development of such a source, based upon photoemission from GaAs, is reviewed in this report.

DOWNLOAD EBOOKThis book contains the proceedings of the third international workshop on From Parity Violation to Hadronic Structure and More. The many applications of parity violation are way beyond the scope of what Lee and Yang could have imagined fifty years after their proposal. For the physics topics discussed during this workshop, the application of parity violation has become a standard work horse allowing for the extraction of many physics topics in different experiments.

DOWNLOAD EBOOKUntil half a century ago, it was assumed that the forces of nature were symmetric and that they did not distinguish between right and left, between image and mirror image. The discovery of the violation of parity in 1956 was more than a sensation, for some it was a shock. It implied that the universe displays handedness, or chirality, and that it is fundamentally asymmetric. Remarkably, a most striking asymmetry is encountered in the realm of biology. Living organisms contain proteins built almost exclusively from L-amino acids, and nucleic acids derived from D-sugars only. Yet a mirror-image biochemistry, based on D-amino acids and L-sugars is, from a purely chemical standpoint, entirely conceivable. Where, then, does this extraordinary natural selectivity come from? Is it directly, or indirectly, connected to the universal violation of parity? This book is meant as a brief review of the various manifestations of handedness, or chirality, in the universe. It does not attempt to present a solution to basic questions which perhaps will never be unambiguously and conclusively answered. Rather, it is an excursion through nature, to observe and recognize how the chirality manifests itself at different structural levels. The excursion starts in the chemistry and physics laboratory. Then a journey into outer space and back in time is undertaken. After a return to our planet Earth, the focus is on the development of living organisms. The text should be accessible to anyone having the equivalent of a first-year university instruction in physics and chemistry. It is also hoped that a layperson with a more modest scientific formation may gain a general impression of the basic asymmetry in nature and of the fundamental significance of chirality. Mathematical expressions, wherever they occur, may then be overlooked. Some more difficult sections may be skipped. A Glossary preceding the Subject Index should be helpful.

DOWNLOAD EBOOKAlmost 50 years after the proposal of Lee and Young in 1956 to test the hypothesis of parity violation in weak interactions and the subsequent experimental verification of parity violation by C. S. Wu, parity violation has today become a useful property of weak interactions. This is due to the fact that the focus nowadays has changed: parity violation in weak interactions is no more a topic of investigation but is used as a tool in many different fields ranging from nuclear physics to the search for the hidden extra dimensions requested by string theory. For our first workshop which took place June 5-8, 2002, at the Institut fiir Ke- physik of the Johannes Gutenberg-Universitat Mainz, we concentrated on the in vestigation of the strangeness contribution in the nucleon. This book contains the refereed and selected papers of the second workshop "From Parity Violation to Hadron Structure and more (Part II)", which took place June 8-11, in the Labo- toire de Physique Subatomique et de Cosmologie, in Grenoble. These papers appear in EPJAdirect, the electronic-only part of EPJA, and they are accessible without restrictions. They will also appear in printed form and can be ordered through Springer. The excellent presentations show the dramatic and steady progress in the accuracy of measured parity violating asymmetries over the last few years.

DOWNLOAD EBOOKThe 20th century has been the century of unparalleled scientific advances fuelled primarily by discoveries made by physicists. The century also represents the life span of the American Physical Society, not coincidentally, and to celebrate both its own centennial and this remarkable century, the APS has prepared this book highlighting the seminal discoveries of the 20th century, with invited articles by the world's most eminent living physicists, including 12 physics Nobel Prize winners. Some 40 chapters cover a broad range of topics in physics written in an engaging and personal style. While the technical level is high, these are not review articles, but rather perspectives on discoveries written by those scientists most closely associated with the original work, as well as future directions of research.
