The Drell-Yan process in NNLO QCD
We consider the production of W and Z bosons in hadron collisions. We present a selection of numerical results obtained through a fully exclusive calculation up to next-to-next-to-leading order (NNLO) in QCD perturbation theory. We include the γ–Z interference, finite-width effects, the leptonic decay of the vector bosons and the corresponding spin correlations. The calculation is completely re...
متن کاملThe Drell - Yan Process and Factorization in Impact Parameter Space ∗
The cross section for Drell-Yan pair production in the limit of small xtarget is derived in the rest frame of the target hadron. Our calculation is based on the fundamental quantity σ(ρ), the cross section for the scattering of a qq̄-pair with fixed transverse separation ρ off a hadronic target. As in deep inelastic scattering the result can be given in terms of integrals of σ(ρ). This is consis...
متن کاملInitial State Interactions , Factorization , and the Drell - Yan Process
We show that initial state interactions violate the factorization conjecture for the Drell-Yan process order by order in perturbation theory. We also discuss the effects of elastic and inelastic initial state interactions on the observed cross sections. A Talk Presented by G. T. Bodwin at the 1981 Banff Summer School on Particles and Fields Alberta, Canada, August 16-28, 1981 * Work supported b...
متن کاملQCD corrections to the longitudinally polarized Drell–Yan process
In this paper we calculate the O(αs) corrections to the xF and y-distributions of lepton pairs produced in collisions of longitudinally polarized hadrons. The numerical importance of these corrections is studied and consequences for the extraction of the polarized sea quark distributions from a measurement of the longitudinally polarized Drell–Yan cross section are discussed. PACS: 13.88.+e;13....
متن کاملPolarized Drell-Yan Process
The results of a recent calculation of the QCD corrections to the longitudinally polarized Drell-Yan process are summarized. In addition to the parity conserving double spin asymmetry which is already accessible in the Drell-Yan production of lepton pairs at fixed target energies, we consider parity violating single spin asymmetries appearing only in the production of massive vector bosons at p...
