This book was released on 1994-01-28 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Workshop on Time Reversal Invariance and Parity Violation in Neutron Reactions focused on the study of parity violation (PV) and time reversal invariance (TRI) in neutron physics. Emphasis was placed on measurements with polarized neutron beams and polarized targets as well as on the implication of recent theoretical developments for the future progress of this rapidly developing and increasingly important field of research.

Available in PDF, EPUB and Kindle. Book excerpt: The existing formalism used to describe spin observables in neutron transmission experiments is found to be inadequate. A suitable formalism is developed, through which time-reversal violating (and parity non-conserving) forward scattering amplitudes are identified, along with their corresponding spin observables. It is noted that new and more precise tests of T-symmetry are provided in transmission experiments and that such investigations are applicable more generally in nuclear and particle physics.

Available in PDF, EPUB and Kindle. Book excerpt: Time reversal invariance violating (TRIV) effects in neutron transmission through a nuclear target are discussed. Here, we demonstrate the existence of a class of experiments that are free from false asymmetries. We discuss the enhancement of TRIV effects for neutron energies corresponding to p-wave resonances in the compound nuclear system. Finaly, we analyze a model experiment and show that such tests can have a discovery potential of 102-104 compared to current limits.

Book excerpt: Time reversal invariance violation plays only a small role in the Standard Model, and the existence of a T-violating effect above the predicted level would be an indication of new physics. A sensitive probe of this symmetry in the weak interaction is the measurement of the T-violating ''D''-correlation in the decay of free neutrons. The triple-correlation D[sigma]{sub n}·p{sub e} x p{sub v} involves three kinematic variables, the neutron spin, electron momentu, and neutrino (or proton) momentum, and changes sign under time reversal. This experiment detects the decay products of a polarized cold neutron beam with an octagonal array of scintillation and solid-state detectors. Data from first run at NIST's Cold Neutron Research Facility give a D-coefficient of -0.1 ± 1.3(stat.) ± 0.7(syst) x 10−3. This measurement has the greatest bearing on extensions to the Standard model that incorporate leptoquarks, although exotic fermion and lift-right symmetric models also allow a D as large as the present limit.

Book excerpt: Experiments to test time-reversal invariance are discussed. The experiments are based on observables constructed from the momentum and spin vectors of epithermal neutrons and from the spin of an aligned or polarized target. It is shown that the proposed tests are detailed balance tests of time-reversal invariance. The status of the experiments is briefly reviewed. 14 refs., 5 figs.

Available in PDF, EPUB and Kindle. Book excerpt: I'll discuss the experiments in which parity violation has been measured in low energy neutron-nucleus scattering. The interest is two-fold: to understand how parity violation in the nucleon-nucleon (NN) interaction manifests itself in a complicated many-body system and to show that the large enhancements observed make this a good laboratory to search for violations of TRI. Further, the procedure of relating the measured parity violating asymmetries to the under-lying NN interaction will be important in order to make the same connection in violation of TRI (or in limits). First, I'll make brief comments on some relevant features of low energy neutron scattering and then review the existing measurements of parity violation. I'll try to explain, at least qualitatively, the origin of the large enhancements observed. Finally, I'll describe the TRIPLE collaboration program to study parity violation and discuss planned experiments to search for violations of TRI. 23 refs.

This book was released on 1996-11-06 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book contains the Proceedings of the 2010 Conference of the Italian Systems Society. Papers deal with the interdisciplinary study of processes of changing related to a wide variety of specific disciplinary aspects. Classical attempts to deal with them, based on generalising approaches used to study the movement of bodies and environmental influence, have included ineffective reductionistic simplifications. Indeed changing also relates, for instance, to processes of acquisition and varying properties such as for software; growing and aging biological systems; learning/cognitive systems; and socio-economic systems growing and developing through innovations. Some approaches to modelling such processes are based on considering changes in structure, e.g., phase-transitions. Other approaches are based on considering (1) periodic changes in structure as for processes of self-organisation; (2) non-periodic but coherent changes in structure, as for processes of emergence; (3) the quantum level of description. Papers in the book study the problem considering its transdisciplinary nature, i.e., systemic properties studied per se and not within specific disciplinary contexts. The aim of these studies is to outline a transdisciplinary theory of change in systemic properties. Such a theory should have simultaneous, corresponding and eventually hierarchical disciplinary aspects as expected for a general theory of emergence. Within this transdisciplinary context, specific disciplinary research activities and results are assumed to be mutually represented as within a philosophical and conceptual framework based on the theoretical centrality of the observer and conceptual non-separability of context and observer, related to logically open systems and Quantum Entanglement. Contributions deal with such issues in interdisciplinary ways considering theoretical aspects and applications from Physics, Cognitive Science, Biology, Artificial Intelligence, Economics, Architecture, Philosophy, Music and Social Systems.
Download or read book Ultra Cold Neutrons written by R. Golub and published by CRC Press. This book was released on 2017-07-12 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultra-Cold Neutrons is a complete, self-contained introduction and review of the field of ultra-cold neutron (UCN) physics. Over the last two decades, developments in UCN technology include the storage of UCN in material and magnetic bottles for time periods limited only by the beta decay rate of the free neutron. This capability has opened up the possibility of a wide range of applications in the fields of both fundamental and condensed state physics. The book explores some of these applications, such as the search for the electric dipole moment of the neutron that constitutes the most sensitive test of time reversal invariance yet devised. The book is suitable as an introduction to the field for research students, as a useful compendium of results and techniques for researchers, and is of general interest to nonspecialists in other areas of physics such as neutron, atomic, and fundamental physics and neutron scattering.
