This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes the determination of the strong coupling constant $\alpha\sb{s}$ from measurements of multi-jet rates in deep inelastic electron-proton scattering at HERA by the ZEUS collaboration for values of the squared four-momentum transfer $Q\sp2$ between 120 and 3600 GeV$\sp2.$ A total integrated luminosity of 3.2 pb$\sp{-1},$ collected during 1994, was used for the measurement. Jets are identified with the JADE algorithm. The jet rates were fitted to a next-to-leading order $O\ (\alpha\sbsp{s}{2})$ perturbative QCD calculation with $\alpha\sb{s}$ left as a free parameter. Using the fitted value for $\alpha\sb{s}$ the perturbative calculation describes well the measured rates and kinematic properties of multi-jet events. A cut on the angular distribution of parton emission in the $\gamma\sp{\*}$-parton center of mass is introduced to remove forward going jets. The value of $\alpha\sb{s}$ is measured in three $Q\sp2$ regions and finally combined over the full kinematic range. The $\alpha\sb{s}$ value decreases for increasing $Q\sp2,$ consistent with the running of the strong coupling constant, as expected by QCD. The determined value is $\alpha\sb{s}\ (M\sb{Z\sp0})=0.117\pm0.005\ (stat)\ \pm\ \sbsp{0.005}{0.004}(syst\sb{exp})\ \pm\ 0.007\ (syst\sb{theory}).$

Download or read book Deep Inelastic Scattering written by Robin Devenish and published by OUP Oxford. This book was released on 2011-04-28 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an up-to-date, self-contained account of deep inelastic scattering in high-energy physics, intended for graduate students and physicists new to the subject. It covers the classic results which led to the quark-parton model of hadrons and the establishment of quantum chromodynamics as the theory of the strong nuclear force, in addition to new vistas in the subject opened up by the electron-proton collider HERA. The extraction of parton momentum distribution functions, a key input for physics at hadron colliders such as the Tevatron at Fermi Lab and the Large Hadron Collider at CERN, is described in detail. The challenges of the HERA data at 'low x' are described and possible explanations in terms of gluon dynamics and other models outlined. Other chapters cover: jet production at large momentum transfer and the determination of the strong coupling constant, electroweak interactions at very high momentum transfers, the extension of deep inelastic techniques to include hadronic probes, a summary of fully polarised inelastic scattering and the spin structure of the nucleon, and finally a brief account of methods in searching for signals 'beyond the standard model'.

This book was released on 2007-01-23 with total page 996 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings present the most up-to-date status of deep inelastic scattering (DIS) physics. Topics such as structure function measurements and phenomenology, quantum chromodynamics (QCD) studies in DIS and photoproduction, spin physics and diffractive interactions are reviewed in detail, with emphasis on those studies that push the test of QCD and the Standard Model to the limits of their present range of validity, towards both the very high and the very low four-momentum transfers in lepton-proton scattering.

This book was released on 1993-08-12 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: By adopting the approach of simulating actual morning report sessions experienced by hospital doctors, Clinical Case Studies in Pediatrics provides a compendium of commonly seen types of pediatrics cases that require hospital admission. Each case study is presented by description of indication of admission to the hospital, the physical examination and laboratory test results, followed by a differential diagnosis, discussion of the differential diagnosis, and finally an in-depth discussion of the actual diagnosis. Study and review questions, which will help medical students or pediatricians-in-training to apply their knowledge, are also included. This book will not only be useful to medical students, it can also be a handy reference for pediatricians and doctors-in-training.

Download or read book Quantum Chromodynamics written by Günther Dissertori and published by Oxford University Press. This book was released on 2003-02-06 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an introduction to Quantum Chromodynamics (QCD), the theory of strong interactions. It covers in full detail both the theoretical foundations and the experimental tests of the theory. Although the experimental chapters focus on recent measurements, the subject is placed into historical perspective by also summarizing the steps which led to the formulation of QCD. Measurements are discussed as they were performed by the LEP experiments at CERN, or at hadron-hadron and lepton-hadron colliders such as the TEVATRON at Fermilab and HERA at DESY. Emphasis is placed on high energy tests of QCD, such as measurements of the strong coupling constant, investigations of the non-abelian structure of the underlying gauge group, determinations of nucleon structure functions, and studies of the non-perturbative hadronization process. This excellent text gives a detailed overview of how QCD developed in the 20th century and where we stand with respect to a quantitative understanding after the turn of the millenium. The text is intended for graduate and postgraduate students as well as researchers, and includes numerous problems and solutions.
