Book excerpt: NSA is a comprehensive collection of international nuclear science and technology literature for the period 1948 through 1976, pre-dating the prestigious INIS database, which began in 1970. NSA existed as a printed product (Volumes 1-33) initially, created by DOE's predecessor, the U.S. Atomic Energy Commission (AEC).

References to books, conference proceedings, papers, patents, dissertations, engineering drawings, and journal articles from worldwide sources are also included. Abstracts and full text are provided if available.

This book was released on 2014 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: We study the scattering of light pseudoscalar mesons (p, K) off charmed mesons (D, D s) in full lattice QCD. The S -wave scattering lengths are calculated using Luscher's finite volume technique. We use a relativistic formulation for the charm quark. For the light quark, we use domain- wall fermions in the valence sector and improved Kogut-Susskind sea quarks. We calculate the scattering lengths of isospin-3/2 D[pi], D s[pi], D s K, isospin-0 DK and isospin-1 DK channels on the lattice. For the chiral extrapolation, we use a chiral unitary approach to next-to-leading order, which at the same time allows us to give predictions for other channels. It turns out that our results support the interpretation of the D*s0(2317) as a DK molecule. At the same time, we also update a prediction for the isospin breaking hadronic decay width G (D*s0(2317)2!D s[pi]) to (133± 22) keV.

Available in PDF, EPUB and Kindle. Book excerpt: We use the light-front quark model to investigate the structure of the scalar mesons, mainly focusing on the three heavy isoscalar states f0(1370), f0(1500), and f0(1710). We comput the spectrum of scalar mesons by diagonalizing a relativized, QCD-inspired model Hamiltonian written in a basis of 25 simple harmonic oscillator states. The masses are then used to perform a mixing analysis which assumes that the heavy isoscalars are mixtures of quarkonia and the scalar glueball. The resulting quark-glue content is used along with the meson wave functions determined from the spectrum to compute the decay rates to pairs of pseudoscalar mesons (two pions, two kaons, two eta mesons). We find that when the glueball contributions to the decays are ignored, the results are in poor agreement with the available data. However, when we estimate the effect of including the glueball contributions in the decays, a solution can be found that matches the data quite well. In this solution, the f0(1710) is mostly glueball (78%) while the f0(1500) and f0(1370) are mostly mixtures of quarkonia. Additionally, in this solution the glueball contributions to kaon and eta final states are significant, while the contributions to the pion final state is negligible. This finding is in agreement with Chanowitz who uses chiral perturbation theory to show that the amplitude for a scalar glueball to decay to a quark-antiquark pair is proportional to the quark mass. This results in a suppression of the pion decay channel compared to the kaon and eta decay channels.

This book was released on 2008 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the present state of knowledge of the anomalous magnetic moment a=(g-2)/2 of the muon. The muon anomalous magnetic moment is one of the most precisely measured quantities in elementary particle physics and provides one of the most stringent tests of relativistic quantum field theory as a fundamental theoretical framework. It allows for an extremely precise check of the standard model of elementary particles and of its limitations.

Download or read book Kaon Physics written by Jonathan L. Rosner and published by University of Chicago Press. This book was released on 2001-01-15 with total page 654 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1947, the first of what have come to be known as "strange particles" were detected. As the number and variety of these particles proliferated, physicists began to try to make sense of them. Some seemed to have masses about 900 times that of the electron, and existed in both charged and neutral varieties. These particles are now called kaons (or K mesons), and they have become the subject of some of the most exciting research in particle physics. Kaon Physics at the Turn of the Millennium presents cutting-edge papers by leading theorists and experimentalists that synthesize the current state of the field and suggest promising new directions for the future study of kaons. Topics covered include the history of kaon physics, direct CP violation in kaon decays, time reversal violation, CPT studies, theoretical aspects of kaon physics, rare kaon decays, hyperon physics, charm: CP violation and mixing, the physics of B mesons, and future opportunities for kaon physics in the twenty-first century.

Download or read book Medium Modifications of Mesons written by Thomas Hilger and published by Sudwestdeutscher Verlag Fur Hochschulschriften AG. This book was released on 2013-01 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interplay of hadron properties and their modification in an ambient nuclear medium on the one hand and spontaneous chiral symmetry breaking and its restoration on the other hand is investigated. QCD sum rules for various heavy-light pseudoscalar mesons embedded in cold nuclear matter are evaluated, the impact of order parameters is investigated and Weinberg type sum rules are derived. The consequences of a chirally symmetric scenario for the rho meson are investigated and the complementarity of mass shift and broadening is discussed. Additionally, the analytic structure of quark propagators in the complex plane is investigated numerically within Dyson-Schwinger equations. The applicability of Bethe-Salpter equations for heavy-light quark-antiquark bound states in the scalar and pseudo-scalar channels by variation of the momentum partitioning parameter is presented. The solutions of the Dyson-Schwinger equation in the Wigner-Weyl phase are used to investigate the hadron spectrum with explicit but without dynamical chiral symmetry breaking. An exhaustive introduction to chiral transformations within classical and quantum field theory and current-current correlators is given.
