This book was released on 1993 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: The D0 experiment has accumulated data for a study of inclusive W production corresponding to a total integrated luminosity of 14.3 ± 1.7 pb−1 during the 1992--1993 Fermilab Tevatron collider run. The total number of W → e + [nu] candidates is 9770. The ratio of the number of W + 1 jet events to that of W + 0 jet events has been measured as a function of jet minimum E{sub T}. Using this ratio the strong coupling constant, [alpha]{sub s} at Q2 = M{sub W}2 is measured to be [alpha]{sub s}(M{sub W}2) = 0.124 ± 0.005(stat) ± 0.006(MC) ± 0.008(theory){sub -0.022}{sup +0.026}(sys) or ({sub -0.025}{sup +0.028} combined) with a jet minimum E{sub T} of 25 GeV. A quantitative test of perturbative QCD has been made by comparing the experimentally measured ratio with the theoretical predictions. The theoretical predictions of the ratio in both the leading order and next-to-leading order are in good agreement with the measured ratio.

This book was released on 2008 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present a new extraction of the effective strong coupling constant $\alpha_{s, g_1}(Q^2)$. The result agrees with a previous determination and extends the measurement of the low and high $Q^2$ behavior of $\alpha_{s, g_1}(Q^2)$ that was previously deduced from sum rules. In particular, it experimentally verifies the lack of $Q^2$-dependence of $\alpha_{s, g_1}(Q^2)$ in the low $Q^2$ limit. This fact is necessary for application of the AdS/CFT correspondence to QCD calculations. We provide a physics motivated parameterization of $\alpha_{s, g_1}(Q^2)$ that can equivalently be used to parameterize the $Q^2$-dependence of the generalized Gerasimov-Drell-Hearn and Bjorken sums.

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.

This book was released on 1994-05-31 with total page 866 pages. Available in PDF, EPUB and Kindle. Book excerpt: This international conference was dedicated to the interface between nuclear and elementary particle physics. It was the thirteenth in a series initiated by T.E.O. Ericson, A. de Shalit and V. F. Weisskopf at CERN in 1963. The series provides the principal international forum for the presentation and critical examination of the main results of the experimental and theoretical research in the field of interest common to nuclear and particle physics. The topics cover the energy region where nucleons must be treated as composite particles, but quarks and gluons cannot be considered asymptotically free.PAN XIII reviews the status of the field in a delicate stage of transition: new experiments and instrumental facilities are bringing in more detailed and more accurate data on the various facets of the nuclear and subnuclear universe, but we are still far from a satisfactory and complete description of nucleons and nuclei in terms of underlying quarks and their interactions.
