Available in PDF, EPUB and Kindle. Book excerpt: In this paper we compute, within in the context of a relativistic quark model, the Isgur-Wise functions for exclusive semileptonic $\bar B \to X_c$ decays, where $X_c$ is any charmed mesons with total spin $J=0,1,2$ or one of their first excited states. The relevant matrix elements are computed by a direct numerical integration, in coordinate space, of the convolution of the wave function of the $B$ meson at rest and the wave function of the $X_c$ meson, boosted according with its recoil factor. Our results are compared with other predictions found in the existing literature.

Available in PDF, EPUB and Kindle. Book excerpt: We present the results of a search for four exclusive semileptonic decays B → D{sup (*)}[tau]−{bar [nu]}{sub [tau]} in 209 fb−1 of data collected with the BABAR detector, corresponding to 232 million e+e- → [Upsilon](4S) → B{bar B} events. We select events with a D{sup (*)} meson and a light lepton (e or [mu]) recoiling against a fully-reconstructed B meson. We perform a fit to the lepton spectrum and missing mass squared to discriminate signal events from backgrounds, predominantly B → D{sup (*)}{tau}−{bar [nu]}{sub {tau}}. A control sample of identified D**l−{bar {nu}}{sub {ell}} events is included in the fit to estimate the background contribution from these decays. We measure [beta](B → D{sub {tau}{nu}}) = (0.86±0.24±0.11±0.06)% and [beta](B → D*{sub {tau}{nu}}) = (1.62±0.31±0.10±0.05)%, where the errors are statistical, systematic, and normalization-mode related, respectively, and where the results are expressed for the {bar B}° lifetime.

This book was released on 1998 with total page 671 pages. Available in PDF, EPUB and Kindle. 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.

Available in PDF, EPUB and Kindle. Book excerpt: "We are interested in measuring the exclusive semileptonic decays of the Ds to greater precision because it is the least extensively studied of the ground state charmed mesons, and greater knowledge of the Ds's decays may give information on related processes. We have studied semileptonic decay of the Ds meson using the full data set collected near the D*sDs peak production energy of 4170 MeV with the CLEO-c detector. We have made improved measurements of the branching fractions of Cabibbo favored semileptonic decays [formula would not render] and [formula would not render]. We have also made observations of the branching fractions of Cabibbo suppressed semileptonic decays [formula would not render] and [formula would not render]. These branching fractions are the most precisely measured to date"--Page vi.

Book excerpt: We have studied semileptonic B meson decays with a P-wave charm meson in the final state using 3.29 x 106 B{bar B} events collected by the CLEO II detector at the Cornell Electron-positron Storage Ring.
