This book was released on 2008 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report the results of a search for the anomalous production of a massive particle decaying to four electrons via two Z° bosons in 1.1 fb−1 of p{bar p} collisions at √s =1.96 TeV collected by the CDF II detector at Fermilab. We employ optimized electron identification criteria to maximize acceptance and efficiency. We estimate the backgrounds in the invariant mass range 500-1000 GeV/c2 to be 0.028 ± 0.009 (stat) ± 0.011 (syst) events. We observe zero events in this search region. Assuming a Randall-Sundrum graviton production model, we set 95% CL limits on? x BF(G → Z°Z°)

Download or read book 60 Years Of Cern Experiments And Discoveries written by Herwig Schopper and published by World Scientific. This book was released on 2015-07-13 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is a compilation of the most important experimental results achieved during the past 60 years at CERN - from the mid-1950s to the latest discovery of the Higgs particle. Covering the results from the early accelerators at CERN to those most recent at the LHC, the contents provide an excellent review of the achievements of this outstanding laboratory. Not only presented is the impressive scientific progress achieved during the past six decades, but also demonstrated is the special way in which successful international collaboration exists at CERN.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We report on a search for anomalous production of Z pairs through a massive resonance decay in data corresponding to 2.5-2.9 fb−1 of integrated luminosity in p{bar p} collisions at √s = 1.96 TeV using the CDF II detector at the Fermilab Tevatron. This analysis, with more data and channels where the Z bosons decay to muons or jets, supersedes the 1.1 fb−1 four-electron channel result previously published by CDF. In order to maintain high efficiency for muons, we use a new forward tracking algorithm and muon identification requirements optimized for these high signal-to-background channels. Predicting the dominant backgrounds in each channel entirely from sideband data samples, we observe four-body invariant mass spectra above 300 GeV/c2 that are consistent with background. We set limits using the acceptance for a massive graviton resonance that are 7-20 times stronger than the previously published direct limits on resonant ZZ production.

Download or read book Search For New Elementary Particles, The: Status And Prospect - Proceedings Of The Trieste Workshop written by Martin Lewis Perl and published by World Scientific. This book was released on 1993-06-14 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been more than a decade since new elementary particles were discovered. To recognize the findings of scientists in this still fairly new but exciting and promising area of research, the Trieste Workshop was organised in May 1992 to discuss the status and explore the prospects for the discovery of new elementary particles using the full variety of search methods which are, or will be available to the physicist. All papers in this collection of proceedings are reviews written by experts in their own area of speciality. Many review papers based on experimental findings are also included. To present a clearer and more coherent overview, a theoretical overview talk as well as a summary talk have been included to serve as a link between the various areas that were discussed in the papers. This collection of papers is perhaps the first authoritative source ever published on the search for new elementary particles.

Download or read book Electron-Positron Physics at the Z written by M. G. Green and published by CRC Press. This book was released on 1998 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive summary of studies of the Z boson in electron positron interactions. The results that have been obtained have achieved unprecedented accuracy and have firmly established the Electroweak Standard Model as the cornerstone of our current understanding of modern particle physics. The book introduces the background to the Standard Model and the role of the Z boson and describes briefly the accelerators and experiments involved in these results. The five main chapters deal with the detailed measurements of the electroweak parameters of the Z, the study of QCD, heavy quark physics, tau lepton physics and the search for new particles. Each chapter ends with a summary and outlook to prospects of future accelerators. Most of the results are from the first six years running at the first phase of electron positron collider, LEP, at energies corresponding to the Z mass, but results from the SLAC Linear Collider and some new results at higher energies are also included.

Book excerpt: We have searched 310 hadronic Z decays for evidence of new quarks and leptons. We set lower mass limits of 40.7 GeV/c2 for top, 45 GeV/c2 for bottom prime, and 42.4 GeV/c2 for a heavy neutral lepton assuming their decays are predominantly via the charged current. Limits are also set for other decay modes and for mixtures of decay modes. 10 refs., 10 figs.
