Abstract

A survey is presented of some current issues of interest in attempts to describe the production of massive lepton pairs in had-ronic collisions at high energies. I concentrate on the interpretation of data in terms of the parton model and on predictions derived from quantum-chromodynamics (QCD), their reliability and their confrontation with experiment. Among topics treated are the connection with deep-inelastic lepton scattering, universality of structure functions, and the behavior of cross-sections as a function of transverse momentum.KeywordsTransverse MomentumStructure FunctionLepton PairAbsolute NormalizationLepton Pair ProductionThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
