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.

This book was released on 2008 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: The branching fractions of decays of the D+s meson normalize many measurements of processes involving charm quarks. Using 298 pb-1 of e+e- collisions recorded by the CLEO-c detector at the Cornell Electron Storage Ring, we determine absolute branching fractions for eight D+s decays with a double tag technique. In particular we determine the branching fraction BD+s & rarr; K-K +pi+) = (5.50 +/- 0.23 +/- 0.16)%, where the uncertainties are statistical and systematic respectively. The uncertainty in these determinations is roughly a factor of two better than previous world averages. We also search for possible CP asymmetries and provide partial branching fractions for kinematic subsets of the K-K+pi + decay mode.

Available in PDF, EPUB and Kindle. Book excerpt: The Lepton-Photon symposiums ? as represented by the contributions in this volume ? are among the most popular conferences in high energy physics since they give an in-depth snapshots of the status of the field as provided by leading experts.The volume covers the latest results on flavor factories, quantum chromodynamics (QCD), electroweak physics, dark matter searches, neutrino physics and cosmology, from a phenomenological point of view. It also offers a glimpse of the immediate future of the field through summaries on the status of the next generation of high energy accelerators and planned facilities for astroparticle physics.The review nature of the articles makes the volume particularly useful to students, as well as being of interest to established researches in high-energy physics and related fields.

Book Synopsis Measurement of the D_s Leptonic Decay Constant F_{D_s} and Observation of New Resonances Decaying to D^(*)pi by : Jose Feliciano Benitez
Download or read book Measurement of the D_s Leptonic Decay Constant F_{D_s} and Observation of New Resonances Decaying to D^(*)pi written by Jose Feliciano Benitez and published by Stanford University. This book was released on 2011 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The absolute branching fractions for the decays $D^-_s\rightarrow\ell^-\bar{\nu}_{\ell}$ ($\ell=e$, $\mu$, or $\tau$) are measured using a data sample corresponding to an integrated luminosity of 521 fb$^{-1}$ collected at center of mass energies near 10.58 GeV with the BABAR detector at the PEP-II $e^+e^-$ collider at SLAC. The number of $D_s^-$ mesons is determined by reconstructing the recoiling system $DKX\gamma$ in events of the type $e^+e^-{\rightarrow}DKXD^{*-}_s$, where $D^{*-}_s\rightarrow D^-_s\gamma$ and $X$ represents additional pions from fragmentation. The $D^-_s\rightarrow\ell^-\nu_{\ell}$ events are detected by full or partial reconstruction of the recoiling system $DKX\gamma\ell$. The following results are obtained: $B(D^-_s \to \mu^- \nu) = (6.02 \pm 0.38 \pm 0.34) \times 10^{-3}$, $B(D^-_s \to \tau^- \nu) = (5.00 \pm 0.35 \pm 0.49) \times 10^{-2}$, and $B(D^-_s \to e^- \nu)
