Available in PDF, EPUB and Kindle. Book excerpt: Neutral current interactions are known from studies of K meson decays to conserve flavor to a high precision. Although flavor changing neutral currents (FCNC) are forbidden in the Weinberg-Salam model, many extensions of the Standard Model allow such processes. We present preliminary upper limits on FCNC-mediated decays of charmed particles, namely D° .-->. ee−, D° .-->. .mu.mu.−, D° .-->. .mu.e and D+ .-->. .pi.+.mu.e.

Download or read book Search for Rare Charm Meson Decays at FNAL E791 written by and published by . This book was released on 2003 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report the results of a blind search for flavor-changing neutral current (FCNC), lepton-flavor violating, and lepton-number violating decays of D, D{sub s}, and D° mesons (and their antiparticles) into 2-, 3-, and 4-body states including a lepton pair. Such decays may involve Flavor-Changing Neutral Currents, Leptoquarks, Horizontal Gauge Bosons, or Majorana Neutrinos. No evidence for any of these decays is found. Therefore, we present 90% confidence level branching-fraction upper limits, typically at the 10−4 level. A total of 51 decay channels have been examined; 26 have not been previously reported and 18 are significant improvements over previous results.

Available in PDF, EPUB and Kindle. Book excerpt: The authors report the results of a blind search for flavor-changing neutral current, lepton-flavor violating, and lepton-number violating decays of D, D{sub s}, and D° mesons (and their antiparticles) into modes containing muons and electrons. Using data from Fermilab charm hadroproduction experiment E791, they examine the [pi]ll and Kll decay modes of D+ and D{sub s}+ and the l+l− decay modes of D°. No evidence for any of these decays is found. Therefore, they present branching-fraction upper limits at 90% confidence level for the 24 decay modes examined. Eight of these modes have no previously reported limits, and fourteen are reported with significant improvements over previously published results.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This work presents a search for three rare/forbidden neutral charm decays, D[sup 0][yields][mu]e, D[sup 0][yields][mu][mu], and D[sup 0][yields] ee. This study was based on data collected in Experiment E789 at the Fermi National Accelerator Laboratory using 800 GeV/c proton-gold interactions. Two statistical analyses are presented, one with background subtraction and the other without background subtraction. No evidence is found for any of the decays and the following upper limits are presented at the 90% confidence level.

Download or read book Search for Flavor-Changing Neutral Current Top Quark Decays t → Hq, with H → bb̅ , in pp Collisions at √s = 8 TeV with the ATLAS Detector written by Shota Tsiskaridze and published by Springer. This book was released on 2017-08-02 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: This PhD thesis focuses on the search for flavor-changing neutral currents in the decay of a top quark to an up-type quark (q = u, c) and the Standard Model Higgs boson, where the Higgs boson decays to bb. Further, the thesis presents the combination of this search for top quark pair events with other ATLAS searches – in the course of which the most restrictive bounds to date on tqH interactions were obtained. Following on from the discovery of the Higgs boson, it is particularly important to measure the Yukawa couplings of the Standard Model fermions; these parameters may provide crucial insights to help solve the flavor puzzle and may help reveal the presence of new physics before it is directly observed in experiments.

Available in PDF, EPUB and Kindle. Book excerpt: We study the flavor-changing-neutral-current process c → u??− using 1.3 fb−1 of p{bar p} collisions at √s = 1.96 TeV recorded by the D0 detector operating at the Fermilab Tevatron Collider. We see clear indications of the D+{sub s} and D+ →??+ →?+?−?+ final states with significance greater than four standard deviations above background for the D+ state. We search for the continuum decay of D+ →?+?+?− in the dimuon invariant mass spectrum away from the? resonance. We see no evidence of signal above background and set a limit of B(D+ →?+?+?−)

Download or read book Heavy Flavor Decays of the Z0 and a Search for Flavor Changing Neutral Currents written by and published by . This book was released on 2004 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presented here are the results of a direct search for flavor changing neutral currents via the rare process Z° → bs and a measurement of R{sub bs} = [Lambda](Z° → bs)/[Lambda](Z° → hadrons). Because the decays Z° → b{bar b} and Z° → c{bar c} contribute significant backgrounds to Z° → bs, simultaneous measurements of R{sub b} = [Lambda](Z° → b{bar b})/[Lambda](Z° → hadrons) and R{sub c} = [Lambda](Z° → c{bar c})/[Lambda](Z° → hadrons) were also made. The standard double tag technique was extended and self calibrating tags were used for s, c, and b quarks. These measurements were made possible by the unique capabilities of the SLAC Large Detector (SLD) at the Stanford Linear Accelerator Center (SLAC): The b and c tags relied upon the SLD's VXD3 307 megapixel CCD vertex detector for topological and kinematic reconstruction of the B and D decay vertices; the s tag identified K{sup {+-}} mesons using the particle identification capabilities of SLD's Cherenkov Ring Imaging Detector (CRID), and K{sub S}° mesons and [Lambda] hadrons by kinematic reconstruction of their decay vertices in SLD's 5120 channel central drift chamber (CDC) particle tracking system.

This book was released on 1997-11-29 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Partial differential equations form an essential part of the core mathematics syllabus for undergraduate scientists and engineers. The origins and applications of such equations occur in a variety of different fields, ranging from fluid dynamics, electromagnetism, heat conduction and diffusion, to quantum mechanics, wave propagation and general relativity.This volume introduces the important methods used in the solution of partial differential equations. Written primarily for second-year and final-year students taking physics and engineering courses, it will also be of value to mathematicians studying mathematical methods as part of their course. The text, which assumes only that the reader has followed a good basic first-year ancillary mathematics course, is self-contained and is an unabridged republication of the third edition published by Longman in 1985.
