Recent experimental data and theoretical developments on the production of lepton pairs in hadron collisions are reviewed. With emphasis on the interplay between theory and experiment, the relevance of theoretical calculations to the data available at present energies is critically examined. The Drell--Yan mechanism is found to be phenomenologically dominant provided that the parton distribution functions contain effects of gluon radiation in a narrow cone. Explicit QCD perturbative calculations of the non-Drell--Yan type yield results that are apparently important at large transverse momenta, but are contradicated by subsequent data at 400 GeV and below. A consistent picture in the parton model is sketched. Further experiments to probe the basic mechanism are suggested. 83 references.

The general features of lepton pair production are reviewed. Physics motivations for precision measurements of lepton pair production in nuclei are discussed. Preliminary results from Fermilab experiment E772 are presented. The relevance of these results to the EMC effects and to J//psi/ suppression in heavy ion collisions is also discussed. 73 refs., 26 figs., 2 tabs.

The hadroproduction of lepton pairs with mass Q and transverse momentum Q{sub T} can be described in perturbative QCD by the same partonic subprocesses as prompt photon production. They demonstrate that, like prompt photon production, lepton pair production is dominated by quark-gluon scattering in the region Q{sub T}> Q/2. This leads to sensitivity to the gluon density in kinematical regimes that are accessible both at collider and fixed target experiments while eliminating the theoretical and experimental uncertainties present in prompt photon production.

A review is presented of recent experimental and theoretical progress in studies of the production of massive lepton pairs in hadronic collisions. I begin with the classical Drell-Yan annihilation model and its predictions. Subsequently, I discuss deviations from scaling, the status of the proofs of factorization in the parton model, higher-order terms in the perturbative QCD expansion, the discrepancy between measured and predicted yields (K factor), high-twist terms, soft gluon effects, transverse-momentum distributions, implications for weak vector boson (W/sup + -/ and Z°) yields and production properties, nuclear A dependence effects, correlations of the lepton pair with hadrons in the final state, and angular distributions in the lepton-pair rest frame.
