This chapter discusses the predictions of Quantum Chromodynamics for event shapes in electron-positron annihilation to hadrons, and in for the evolution of parton distributions, and the comparison of these predictions to experiment. It introduces the notion of a jet of hadrons associated with a hard-scattered parton.

This chapter describes the description of the proton as a bound state of partons. After a review of the properties of parton distribution functions, it introduces the evidence for a component of the proton responsible for its binding. It introduces the model of strong interactions as mediated by a spin 1 gluon and presents the evidence for this model from event shapes in electron-positron annihilation to hadrons.

AbstractEvent shapes are classical tools for the determination of the strong coupling and for the study of hadronization effects in electron-positron annihilation. In the context of analytical studies, hadronization corrections take the form of power-suppressed contributions to the cross section, which can be extracted from the perturbative ambiguity of Borel-resummed distributions. We propose a simplified version of the well-established method of Dressed Gluon Exponentiation (DGE), which we call Eikonal DGE (EDGE), which determines all dominant power corrections to event shapes by means of strikingly elementary calculations. We believe our method can be generalized to hadronic event shapes and jet shapes of relevance for LHC physics.
