Book excerpt: The recent CLEO-c results on hadronic decays of D and D{sub s} mesons are presented. First the absolute branching fractions for D and D{sub s} mesons using a double tag technique are discussed, then are the Cabibbo suppressed decays and doubly Cabibbo suppressed decays. Finally, I present the inclusive and rare decay modes and other measurements from CLEO-c. These decays illuminate a wide range of physics. A brief theoretical introduction is given before the corresponding discussion on measurement.

Download or read book Semileptonic Decays of Charged D Meson Going to Eta lepton neutrino with Generic Reconstruction of Fully Hadronic Charged D Meson and Neutral D Meson Decays written by Richard Carl Gray and published by . This book was released on 2008 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: We study the semileptonic decays D + & rarr; eta'e+nu and D+ & rarr; etae+nu using 818 pb-1 of e+ e- collisions recorded by the CLEO-c detector located at the Cornell Electron Storage Ring. We employ a technique that uses the detector hermeticity to reconstruct the neutrino as missing energy and momentum. We improve the neutrino resolution by developing a generic algorithm to reconstruct the non-signal D, and constrain systematic uncertainties in the efficiency by using the algorithm to measure the branching fractions of D+ and D0 hadronic decays. We observe and measure the branching fractions of 67 hadronic decays, 32 of which are not listed in the PDG 2008. We find B (D+ & rarr; eta'e +nu) = (2.16 +/- 0.53 +/- 0.05 +/- 0.05) x 10-4 and B (D+ & rarr; etae +nu) = (11.7 +/- 0.98 +/- 0.34 +/- 0.26) x 10-4. Among the 67 D hadronic branching fractions observed in this analysis, we discover the decay B (D+ & rarr; pi+etaeta) = (0.34 +/- 0.06 +/- 0.032)% which is unexpectedly large considering the limited phase space available to the decay.

This book was released on 2010-01-11 with total page 1010 pages. Available in PDF, EPUB and Kindle. Book excerpt: CIPANP 2009 explores areas of common interest between nuclear physicists, high energy (particle) physicists and astrophysicists. These areas range from studies of the strong interactions that bind nuclei together to physics of the very early Universe and include such topics as neutrinos, hadron physics, spin physics, heavy ion physics, QCD and heavy flavor physics. The Conference papers include descriptions of searches for "new physics", phenomena that cannot be accounted for by current theories.

Download or read book B Decays written by Sheldon Stone and published by World Scientific. This book was released on 1994 with total page 676 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 2nd edition is an extensive update of "B Decays?. The revisions are necessary because of the extensive amount of new data and new theoretical ideas. This book reviews what is known about b-quark decays and also looks at what can be learned in the future.The importance of this research area is increasing, as evidenced by the approval of the luminosity upgrade for CESR and the asymmetric B factories at SLAC and KEK, and the possibility of experiments at hadron colliders.The key experimental observations made thus far, measurement of the lifetimes of the different B species, B0-B0 mixing, the discovery of ?Penguin? mediated decays, and the extraction of the CKM matrix elements Vub and Vcb from semileptonic decays, as well as more mundane results, are described in great detail by the experimentalists who have been closely involved with making the measurements. Theoretical progress in understanding b-quark decays using HQET and lattice gauge techniques are described by theorists who have developed and used these techniques.Synthesizing the experimental and theoretical information, several articles discuss the implications for the ?Standard Model? and how further tests can be done using measurements of CP violation in the B system.

Available in PDF, EPUB and Kindle. Book excerpt: High precision measurements of weak neutral current and charged current processes and of the properties of the Z and W bosons have established the standard electroweak model as correct down to a distance scale of 10-16 cm, and are a sensitive probe of possible underlying physics. In this book, all aspects of the program are considered in detail, including the structure of the standard model, radiative corrections, high precision experiments, and their implications. The major classes of experiments are surveyed, covering the experiments themselves, the data analysis, results, and prospects.This volume is a detailed reference for theoretical and experimental researchers, as well as an introductory text for advanced students.

Book excerpt: The lectures collected in this book present a comprehensive review of the current knowledge of heavy-quark physics, from the points of view of both theory and experiment. Heavy Flavour Physics has accomplished enormous progress during the last few years: the last heavy quark has been discovered and the quality of the collected data on the other relatively lighter quarks has dramatically improved. On the theory side, noticeable progress has been reported on new calculations of decay rates based on various techniques, such as QCD sum rules, heavy-quark mass expansion and lattice QCD. The theory of heavy quark production is constantly improving and awaiting new results. Nevertheless there are strong reasons to believe that the Standard Model of High Energy Physics is incomplete. It exhibits very peculiar patterns for which it offers no explanation. The basic constituents of matter are arranged into three seemingly identical generations or families of quarks and leptons, differing merely in their masses. The pattern in the fermion masses, why they are families and why there are three of them is not yet understood. Furthermore it is known that at least within the standard model there is an intimate connection between the replication of families and the gateway of CP violation, in addition, the latter phenomenon is a crucial ingredient in explaining why our universe is made up almost exclusively of matter rather than being more or less matter-antimatter symmetric. How and to what extent can Heavy Flavour Physics impact on these questions? Does it offer novel windows onto New Physics beyond the Standard Model in general and onto new symmetries, such as Supersymmetry in particular? These questions constitute the central theme of this book. The material treated in this publication may serve as reference for the segment of the high-energy community actively engaged in heavy-quark physics.
