Available in PDF, EPUB and Kindle. Book excerpt: Searching for and potential discovery of Higgs boson(s) both within and beyond the standard model is perhaps the most visible physics goal of the current Fermilab Tevatron program. In this proceeding, recent results from both the CDF and D0 experiments based on analyses of datasets with integrated luminosities between 1.7 and 3.0 fb−1 are summarized. The combined Tevatron cross section upper limits on the production of a standard model Higgs boson are fast approaching the expected standard model values for a wide mass range. Particularly, the Tevatron has now excluded a standard model Higgs boson with a mass of 170 GeV at 95% C.L.

Book Synopsis A Search for the Higgs Boson in the ZH Channel with the D-zero Detector at the Fermilab Tevatron Collider by : James Matthew Heinmiller
Download or read book A Search for the Higgs Boson in the ZH Channel with the D-zero Detector at the Fermilab Tevatron Collider written by James Matthew Heinmiller and published by . This book was released on 2006 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: This analysis describes a search for a standard model Higgs boson produced in association with a Z boson through the decay mode ZH → e+e -bb in pp collisions at s = 1.96 TeV at the Fermilab Tevatrot Collider. The data sample used in this analysis corresponds to 452 pb-1 of integrated luminosity accumulated with the DO detector. Agreement between data and standard model predictions is observed. A 95% confidence level upper exclusion limit for the sigma(pp → ZH x BR(H → bb) channel is set between 3.2--8.2 pb for Higgs masses of 105 to 145 GeV.
Book Synopsis Search for a Higgs Boson Produced in Association with a Z Boson in P Anti-p Collisions by :
Download or read book Search for a Higgs Boson Produced in Association with a Z Boson in P Anti-p Collisions written by and published by . This book was released on 2007 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: We describe a search for the standard model Higgs boson with a mass of 105 GeV/c2 to 145 GeV/c2 in data corresponding to an integrated luminosity of approximately 450 pb−1 collected with the D0 detector at the Fermilab Tevatron p{bar p} collider at a center-of-mass energy of 1.96 TeV. The Higgs boson is required to be produced in association with a Z boson, and the Z boson is required to decay to either electrons or muons with the Higgs boson decaying to a b{bar b} pair. The data are well described by the expected background, leading to 95% confidence level cross section upper limits [sigma]p{bar p} → ZH x B(H → b{bar b}) in the range of 3.1 pb to 4.4 pb.

Available in PDF, EPUB and Kindle. Book excerpt: A search for the production of neutral Higgs bosons ? decaying into ?+?− final states in p{bar p} collisions at a center-of-mass energy of 1.96 TeV is presented. The data, corresponding to an integrated luminosity of approximately 325 pb−1, were collected by the D0 experiment at the Fermilab Tevatron Collider. Since no excess compared to the expectation from standard model processes is found, limits on the production cross section times branching ratio are set. The results are combined with those obtained from the D0 search for ?b({bar b}) → b{bar b}b({bar b}) and are interpreted in the minimal supersymmetric standard model.
Book Synopsis The Higgs Boson by : Scientific American Editors
Download or read book The Higgs Boson written by Scientific American Editors and published by Scientific American. This book was released on 2012-09-30 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Higgs Boson: Searching for the God Particle by the Editors of Scientific American Updated 2017 Edition! For the fifth anniversary of one of the biggest discoveries in physics, we’ve updated this eBook to include our continuing analysis of the discovery, of the questions it answers and those it raises. As the old adage goes, where there’s smoke, there’s fire. Where there is effect, there must be cause. The planet Neptune was found in 1846 because the mathematics of Newton's laws, when applied to the orbit of Uranus, said some massive body had to be there. Astronomers eventually found it, using the best telescopes available to peer into the sky. This same logic is applied to the search for the Higgs boson. One consequence of the prevailing theory of physics, called the Standard Model, is that there has to be some field that gives particles their particular masses. With that there has to be a corresponding particle, made by creating waves in the field, and this is the Higgs boson, the so-called God particle. This eBook chronicles the search – and demonstrates the power of a good theory. Based on the Standard Model, physicists believed something had to be there, but it wasn't until the Large Hadron Collider was built that anyone could see evidence of the Higgs – and finally in July 2012, they did. A Higgs-like particle was found near the energies scientists expected to find it. Now, armed with better evidence and better questions, the scientific process continues. This eBook gathers the best reporting and analysis from Scientific American to explain that process – the theories, the search, the ongoing questions. In essence, everything you need to know to separate Higgs from hype.
Book Synopsis Recent Results on the Top Quark from the Tevatron Collider Experiments by :
Download or read book Recent Results on the Top Quark from the Tevatron Collider Experiments written by and published by . This book was released on 1999 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents the latest measurements of the properties of the top quark as determined by the DØ and CDF collaborations at the Fermilab Tevatron p{anti p} Collider. Both experiments have studied the all-hadronic decay mode of t{anti t} events. The top quark mass measurement has been refined over the past year, with the addition of new channels and a re-evaluation of some of the earlier ones. There are recent studies of the mass of the t{anti t} system, the helicity of the W bosons in the top quark decays, and of the correlation of the spins of the top and antitop quarks. New results are also reported on searches for charged Higgs bosons in top quark decay, and for electroweak production of single top quarks.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We present a search for associated Higgs boson production in the process p{anti p} → W/ZH → l{sup {+-}} l{sup {+-}} + X in ee, e[mu], and [mu][mu] final states. The search is based on data collected by the D0 experiment at the Fermilab Tevatron Collider at √{ovr s} = 1.96 TeV corresponding to 5.3 fb−1 of integrated luminosity. We require two isolated leptons (electrons or muons) with the same electric charge and additional kinematic requirements. No significant excess above background is observed, and we set 95% C.L. observed (expected) upper limits on ratio of the production cross sectin to the standard model expectation of 6.4 (7.3) for a Higgs boson mass of 165 GeV and 13.5 (19.8) for a mass of 115 GeV.

Book excerpt: An accessible look at the hottest topic in physics and the experiments that will transform our understanding of the universe The biggest news in science today is the Large Hadron Collider, the world's largest and most powerful particle-smasher, and the anticipation of finally discovering the Higgs boson particle. But what is the Higgs boson and why is it often referred to as the God Particle? Why are the Higgs and the LHC so important? Getting a handle on the science behind the LHC can be difficult for anyone without an advanced degree in particle physics, but you don't need to go back to school to learn about it. In Collider, award-winning physicist Paul Halpern provides you with the tools you need to understand what the LHC is and what it hopes to discover. Comprehensive, accessible guide to the theory, history, and science behind experimental high-energy physics Explains why particle physics could well be on the verge of some of its greatest breakthroughs, changing what we think we know about quarks, string theory, dark matter, dark energy, and the fundamentals of modern physics Tells you why the theoretical Higgs boson is often referred to as the God particle and how its discovery could change our understanding of the universe Clearly explains why fears that the LHC could create a miniature black hole that could swallow up the Earth amount to a tempest in a very tiny teapot "Best of 2009 Sci-Tech Books (Physics)"-Library Journal "Halpern makes the search for mysterious particles pertinent and exciting by explaining clearly what we don't know about the universe, and offering a hopeful outlook for future research."-Publishers Weekly Includes a new author preface, "The Fate of the Large Hadron Collider and the Future of High-Energy Physics" The world will not come to an end any time soon, but we may learn a lot more about it in the blink of an eye.

This book was released on 2006 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report a search for the standard model (SM) Higgs boson based on data collected by the D0 experiment at the Fermilab Tevatron Collider, corresponding to an integrated luminosity of 260 pb−1. We study events with missing transverse energy and two acoplanar b-jets, which provide sensitivity to the ZH production cross section in the [nu]{bar [nu]}B{bar b} channel and to WH production, when the lepton from the W → l{nu} decay is undetected. The data are consistent with the SM background expectation, and we set 95% C.L. upper limits on [sigma](p{bar p} → ZN/WH) x B(H → b{bar b}) from 3.4/8.3 to 2.5/6.3 pb, for Higgs masses between 105 and 135 GeV.

Book Synopsis Search for Quirks at the Fermilab Tevatron Collider by :
Download or read book Search for Quirks at the Fermilab Tevatron Collider written by and published by . This book was released on 2010 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report results of a search for particles with anomalously high ionization in events with a high transverse energy jet and large missing transverse energy in 2.4 fb−1 of integrated luminosity collected by the D0 experiment at the Fermilab Tevatron p{bar p} collider. Production of such particles (quirks) is expected in scenarios with extra QCD-like SU(N) sectors, and this study is the first dedicated search for such signatures. We find no evidence of a signal and set a lower mass limit of 107 GeV for the mass of a charged quirk with strong dynamics scale [Lambda] in the range from 10 keV to 1 MeV.

Download or read book Searches for the Higgs Boson at the Tevatron Collider written by and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The D0 and CDF experiments at the Tevatron have sought the Higgs boson in data collected till 1996, and have set limits to its existence. After a major upgrade of both detectors and substantial improvements of the acceleration complex, the two experiments have restarted collecting physics quality data in early 2002. It is expected that a Standard Model Higgs boson with mass lower than 180 GeV will be either discovered or ruled out with five years of running.
