This book was released on 2003 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document describes the search for second-generation leptoquarks (LQ{sub 2}) in around 114pb{sup -1} of p{bar p} collisions, recorded with the D0 detector between September 2002 and June 2003 at a centre-of-mass energy of {radical}s = 1.96TeV. The predictions of the Standard Model and models including scalar leptoquark production are compared to the data for various kinematic distributions. Since no excess of data over the Standard Model prediction has been observed, a lower limit on the leptoquark mass of M{sub LQ{sub 2}}{sup {beta}=1}> 200GeV has been calculated at 95% confidence level (C.L.), assuming a branching fraction of {beta} = BF(LQ{sub 2} {yields} {mu}j) = 100% into a charged lepton and a quark. The corresponding limit for {beta} = 1/2 is M{sub LQ{sub 2}}{sup {beta}=1/2}> 152 GeV. Finally, the results were combined with those from the search in the same channel at D0 Run I. This combination yields the exclusion limit of M{sub LQ{sub 2}}{sup {beta}=1}> 222 GeV (177GeV) for (beta) = 1 (1/2) at 95% C.L., which is the best exclusion limit for scalar second-generation leptoquarks (for {beta} = 1) from a single experiment to date.

Book excerpt: In the study presented in this document, about 114 pb[sup -1] of p[bar p] collisions from Run II, collected with the D0 detector between September 2002 and June 2003, are compared to Standard-Model predictions and predictions from models including scalar second-generation leptoquarks. since no deviation from the Standard Model is observed, upper limits on the leptoquark cross-section are calculated and translated into lower bounds to the mass of scalar leptoquarks. Consequently, the results are combined with earlier results from D0 Run I in the same channel.
Download or read book Proton antiproton Collider Physics written by G. Altarelli and published by World Scientific. This book was released on 1989 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume reviews the physics studied at the CERN proton-antiproton collider during its first phase of operation, from the first physics run in 1981 to the last one at the end of 1985.The volume consists of a series of review articles written by physicists who are actively involved with the collider research program. The first article describes the proton-antiproton collider facility itself, including the antiproton source and its principle of operation based on stochastic cooling.The subsequent six articles deal with the various physics subjects studied at the collider. Each article describes in detail the experimental results on a particular subject, and also provides the theoretical framework necessary for their interpretation. Finally the last two articles discuss the physics expectations from the improved collider (the so-called ACOL program, which has just started operation), and also from the next generation of ?supercolliders? which are being considered both in Europe and in the United States America.

This book was released on 2013-03-12 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: The third course of the International School on Physics with Low Energy Antiprotons was held in Erice, Sicily at the Ettore Majorana Centre for Scientific Culture, from 10 to 18 June, 1988. The School is dedicated to physics accessible to experiments using low energy antiprotons, especially in view of operation of the LEAR facility at CERN with the upgraded antiproton source AAC (Antiproton Accumulator AA and Antiproton Collector ACOL). The first course in 1986 covered topics related to fundamental symmetries; the second course in 1987 focused on spectroscopy of light and heavy quarks. This book con tains the Proceedings of the third course, devoted to the experimental and theoretical aspects of the interaction of antinucleons with nucleons and nuclei. The Proceedings contain both the tutorial lectures and contributions presented by participants during the School. The papers are organized in several sections. The first section deals with the theoretical aspects of NN scattering and annihilation, and the underlying QCD. The experimental techniques and results concerning NN scattering are contained in Section II. Section III contains theoretical reviews and contributions on anti proton-nucleus scattering and bound states. Section IV is devoted to the experimental results on the antiproton nucleus systems and their phenomenological analysis. Finally, some possible developments of the antiproton machines are presented.

Download or read book Low Energy Electrons written by Oddur Ingólfsson and published by CRC Press. This book was released on 2019-04-23 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-energy electrons are ubiquitous in nature and play an important role in natural phenomena as well as many potential and current industrial processes. Authored by 16 active researchers, this book describes the fundamental characteristics of low-energy electron–molecule interactions and their role in different fields of science and technology, including plasma processing, nanotechnology, and health care, as well as astro- and atmospheric physics and chemistry. The book is packed with illustrative examples, from both fundamental and application sides, features about 130 figures, and lists over 800 references. It may serve as an advanced graduate-level study course material where selected chapters can be used either individually or in combination as a basis to highlight and study specific aspects of low-energy electron–molecule interactions. It is also directed at researchers in the fields of plasma physics, nanotechnology, and radiation damage to biologically relevant material (such as in cancer therapy), especially those with an interest in high-energy-radiation-induced processes, from both an experimental and a theoretical point of view.
