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.

Recent experiments seem to be ready to answer the question whether QCD be the correct theory of strong interactions at all scales, or just an effective high-energy line of a yet undiscovered theory. With the upgraded Large Hadron Collider, a proton-proton collision will reach the Center of Mass (CoM) energy of 14 TeV per colliding pair. Perturbative QCD will then be tested with the highest precision. In this realm, the present book begins reviewing QCD with the aim to focus on the Drell-Yan process and the experiments conceived to validate it. In doing this the approach will be exclusively perturbative. Non perturbative techniques, such as lattice QCD, QCD sum rules, or concepts like the MIT bag model will not be discussed.
