Download or read book Recent D-Zero Results on the Top Quark written by and published by . This book was released on 1997 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent results on top quark physics with the D0 experiment in {anti p}p collisions at √s = 1.8 TeV for an integrated luminosity of 125 pb−1 are reported. The direct measurement of the top quark mass uses single lepton events, giving the result m{sub top} = 173.3 ± 5.6(stat) ± 6.2(syst) GeV=c2. The measurement of the t{anti t} production cross section includes analyses from 8 top decay channels: dilepton (t{anti t} → e[mu], ee, and [mu][mu]), electron and neutrino (t{anti t} → e[nu]), and single leptons (t{anti t} → e + jets and t{anti t} → [mu] + jets) with and without b tagging. We measure the t{anti t} production cross section to be 5.5 ± 1.8 pb at m{sub top} = 173.3 GeV/c2.

Book Synopsis The Evidence for the Top Quark by : Kent W. Staley
Download or read book The Evidence for the Top Quark written by Kent W. Staley and published by Cambridge University Press. This book was released on 2004-04-05 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Evidence for the Top Quark offers both a historical and philosophical perspective on an important recent discovery in particle physics: the first evidence for the elementary particle known as the top quark. Drawing on published reports, oral histories, and internal documents from the large collaboration that performed the experiment, Kent Staley explores in detail the controversies and politics that surrounded this major scientific result.At the same time the book seeks to defend an objective theory of scientific evidence based on error probabilities.

Book Synopsis Combining the Top Quark Mass Results for Run 1 from CDF and D-Zero by :
Download or read book Combining the Top Quark Mass Results for Run 1 from CDF and D-Zero written by and published by . This book was released on 1999 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: CDF and D0 have published or submitted for publication eleven papers [1-11] that include direct experimental measurements of the top quark mass. Each experiment has found that the lepton+jets channel [1,5,6,9,10,11,12] gives the most precise result. However, CDF and D0 have also measured the top quark mass in other decay topologies. Both D0 [2,6] and CDF [3,4] have published additional results in the dilepton channels, while CDF [8] has published a result in the all-hadronic channel. Our aim in this note is to reduce the overall uncertainty on the top quark mass measurement by combining the most recent and final of these measurements [1,2,3,7,8]. This note combines the mass from the five separate measurements taking into account the statistical and systematic uncertainties as well as the correlations in the systematic uncertainties. The final Tevatron top mass based on Run 1 data is m{sub t} = 174.3 " 3.2(stat) " 4.0(syst) GeV/c2. Combining the statistical and systematic uncertainties, the top mass is m{sub t} = 174.3 " 5.1 GeV/c2.
Book Synopsis 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 by : Shota Tsiskaridze
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.
Book Synopsis Recent Advances In The Superworld - Proceedings Of The International Workshop by : J L Lopez
Download or read book Recent Advances In The Superworld - Proceedings Of The International Workshop written by J L Lopez and published by World Scientific. This book was released on 1994-03-29 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: The realization that precision LEP data lend support to the idea of supersymmetric grand unification and supersymmetry in general, led to the organization of the First HARC International Workshop on Recent Advances in the SuperWorld. The idea was to have a workshop that discussed all aspects of the supersymmetric world — the SuperWorld as it should be properly known. These aspects are so diverse that they are usually studied by high energy physicists with vastly different interests. The selection of speakers included the whole spectrum in 'energy', from experimental physicists, to specialists in low energy phenomenology, supersymmetric grand unification, supergravity, superstrings and supercosmology.

Download or read book Quinta Essentia - Part 3 (2nd Ed.) written by Riccardo Storti and published by Lulu.com. This book was released on 2008-06-30 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Practical Guide to Space-Time Engineering: Particle physics is a rapidly expanding and highly dynamic sphere of knowledge supporting a landscape of constantly changing hues. Experimental boundaries are being shifted with exciting reductions in uncertainty at a staggering pace. This text develops the Electro-Gravi-Magnetic (EGM) construct to define relationships between the distributions of mass-energy over space-time of fundamental particles. The correlation of EGM calculations for mass & "size" to experimental evidence is astonishing, to at least four orders of magnitude greater that can be physically measured. Most of the contents herein have been peer reviewed & published in scientific literature. For particle enthusiasts, this text is a must.

Available in PDF, EPUB and Kindle. Book excerpt: We utilise principles of mass-energy distribution and similitude by ZPF equilibria to derive the values of the present Hubble constant "H0" and CMBR temperature "T0". It is demonstrated that a mathematical relationship exists between the Hubble constant and CMBR temperature such that "T0" is derived from "H0". The values derived are "67.0843(km/s/Mpc)" and "2.7248(K)" respectively. We also derive improved estimates for the solar distance from the Galactic centre "Ro" and total Galactic mass "MG" as being "8.1072(kpc)" and "6.3142 x10^11(solar-masses)" respectively. The construct herein implies that the observed "accelerated expansion" of the Universe is attributable to the determination of the ZPF energy density threshold "U_ZPF" being "

This book was released on 2016-04-13 with total page 5054 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book includes numerous calculations for the many specific examples included within. I have included the many calculated examples to provide the reader with immediate justifications for the numerous concepts described. This was not done to belittle or talk down to the reader but rather to give the reader a clear sense of the plausibility for the propulsion methods and performance capabilities thereof. Interstellar travel at the many specific highly relativistic velocities contemplated in this bookand, in some cases, extreme vehicle massesis still a very controversial subject but nonetheless a highly mathematicalized and intelligible subject. My hope and intention is to thus clearly inspire and show the reader the plausibility of the concepts by providing the reader with proper evidence through his or her simple inspection of the formulas and values included in the computations. Some speculative physics is included, which is based on commonly presented theoretical constructs.
