Download Determination Of[alpha][sub S](M[sub Z][sup 2] from Hadronic Event Shape Observables in E[sup+]e[sup[minus] Annihilation Book in PDF, ePub and Kindle
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.

Download Precise Measurement of the Total Cross Section Book in PDF, ePub and Kindle
This note will analyze the problems involved in making a precise measurement of the total cross secton for ee− annihilation into hadrons. Based on this analysis, we will suggest that a relatively simple non-magnetic device employing calorimetry over a 4.pi. solid angle is the optimum apparatus for such a measurement. We will describe one such device in some detail.
