Book excerpt: 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.

This book was released on 1978 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A review is presented of theoretical attempts to describe the massive lepton pair continuum produced in hadronic collisions. Beginning with the classical Drell-Yan quark-antiquark annihilation model, its expectations are compared with data. Scaling violations and corrections to the Drell-Yan pictured are discussed. Next, original work is presented bearing on the understanding of the transverse momentum distributions of the dileptons. In a parton model, the quark-gluon scattering graphs which provide scaling violations also endow the dileptons with relatively large (P/sub T/). Comparisons with available data support these QCD expectations; further tests of the QCD predictions are proposed. Implications are drawn for W production experiments, and predictions are presented for reactions initiated by antiprotons.

Download or read book Hadroproduction of Massive Lepton Pairs and Tests of QCD Transverse Momentum Distribution Dependence written by and published by . This book was released on 1978 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests of quantum chromodynamics are proposed in the production of massive lepton pairs in hadronic collisions. Predictions are presented for the manner in which the transverse momentum distribution of the pair should change with changes in the mass and longitudinal momentum of the pair, and with changes in the overall energy of the collision. Data are shown to determine the average gluon momentum distribution in the nucleon. Lepton pair production in .pi. N and anti p N processes provides a method to isolate a gluon jet. 20 references.

Book excerpt: The authors discuss the transverse momentum distribution for the production of massive lepton-pairs in hadron reactions at fixed target and collider energies within the context of next-to-leading order perturbative quantum chromodynamics. For values of the transverse momentum Q{sub T} greater than the pair mass Q, Q{sub T}> Q, they show that the differential cross section is dominated by subprocesses initiated by incident gluons. Massive lepton-pair differential cross sections are an advantageous source of constraints on the gluon density, free from the experimental and theoretical complications of photon isolation that beset studies of prompt photon production. They compare calculations with data and provide predictions for the differential cross section as a function of Q{sub T} in proton-antiproton reactions at center-of-mass energies of 1.8 TeV, and in proton-nucleon reactions at fixed target and LHC energies.

Book excerpt: 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.
