This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most important tasks in high energy physics is the precise determination of the strong coupling[alpha][sub s](M[sub Z][sup 2]). Not only does measurement of[alpha][sub s](M[sub Z][sup 2]) in different hard processes and at different hard scales Q provide a fundamental test of the theory of strong interactions, Quantum Chromodynamics (QCD), but it also allows constraints on extensions to the Standard Model of elementary particles. Here, the determination of[alpha][sub s](M[sub Z][sup 2]) using O([alpha][sub s][sup 2]) calculations of hadronic event shape observables in e[sup+]e[sup[minus]] annihilation is reviewed. The large scatter among[alpha][sub s](M[sub Z][sup 2]) values determined from different observables may be interpreted as arising from the effect of uncalculated higher-order contributions. The application of optimized perturbation theory and Pade approximants in an attempt to reduce this effect is discussed.

Available in PDF, EPUB and Kindle. Book excerpt: The authors have measured the strong coupling [alpha]{sub s} using hadronic decays of Z° bosons collected by the SLD experiment at SLAC. The data were compared with QCD predictions both at fixed order, O([alpha]{sub s}2), and including resummed analytic formulae based on the leading and next-to-leading logarithm approximation. The study includes event shapes, jet rates, and particle correlations. They checked the consistency between [alpha]{sub s} extracted from these different measures and found the dominant uncertainty on [alpha]{sub s} to be from uncalculated higher order contributions.

Available in PDF, EPUB and Kindle. Book excerpt: A measurement of the strong coupling constant [alpha][sub s] using the event-shape variable y[sub 3] (the differential two-jet rate) in the reaction e[sup +]e[sup [minus]] [yields] hadrons is presented. The analysis is based on data from the TPC/Two-Gamma detector at the PEP e[sup +]e[sup [minus]] storage ring taken between 1984 and 1986 at a center-of-mass energy of E[sub cm] = 29 GeV. A value of [alpha][sub s](29 GeV) = 0.160 [+-] 0.012 is obtained, where the error is the quadratic sum of experimental and theoretical uncertainties. The procedure for determining [alpha][sub s] is the same as that used by the ALEPH and TOPAZ experiments, which allows for a consistent comparison of the [alpha][sub s] values obtained at different center-of-mass energies. The observed energy dependence [open-quotes]running[close-quotes] of [alpha][sub s] is found to be in good agreement with the QCD prediction, and is clearly incompatible with a constant value.

Available in PDF, EPUB and Kindle. Book excerpt: This will be a required acquisition text for academic libraries. More than ten years after its discovery, still relatively little is known about the top quark, the heaviest known elementary particle. This extensive survey summarizes and reviews top-quark physics based on the precision measurements at the Fermilab Tevatron Collider, as well as examining in detail the sensitivity of these experiments to new physics. Finally, the author provides an overview of top quark physics at the Large Hadron Collider.
