We prove that it is necessary to introduce the non-zero gluon masses into the fundamental Lagrangian of Quantum Chromodynamics in order to describe the mass-gap in the reaction of electron-positron annihilation into hadrons. A new restriction on the gluon masses is obtained. The renormalized theory with non-zero Lagrangian gluon masses is constructed.

Momentum Transfer Range

Experimental results from deep inelastic lepton—nucleon scattering, from electron - positron annihilation to hadrons and from massive lepton - pair production in hadron collisions, are discussed. The data obtained so far give qualitative support for Q C D . Serious quantitative comparisons are beset with difficulties, which arise first because of discrepancies between different experiments, and secondly because in addition to the perturbative effects that have been calculated theoretically, there are non-perturbative contributions for which there are no reliable estimates. These appear to be important in the momentum transfer range that can be investigated experimentally at present.

Event Shapes

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.
