Dilepton rapidity distribution in the Drell-Yan process at NNLO in QCD
We compute the rapidity distribution of the virtual photon produced in the Drell-Yan process through next-to-next-to-leading order in perturbative QCD. We introduce a powerful new method for calculating differential distributions in hard scattering processes. This method is based upon a generalization of the optical theorem; it allows the integration-by-parts technology developed for multi-loop...
متن کاملThreshold resummation of Drell-Yan rapidity distributions
We present a derivation of the threshold resummation formula for the Drell-Yan rapidity distribution. Our argument is valid for all values of rapidity and to all orders in perturbative QCD and can be applied to all Drell-Yan processes in a universal way, i.e. both for the production of a virtual photon γ∗ and the production of a vector boson W±, Z. We show that for the fixedtarget experiment E8...
متن کاملDrell{Yan Dileptons at RHIC
The study if the production of dilepton pairs is an important component of the research to be accomplished at the Relativistic Heavy Ion Collider (RHIC) due to each relevance to Quark-Gluon Plasma search and the investigation of hard QCD processes. We present an event generator program that produces Drell-Yan dilepton pairs for symmetric heavy ion collisions. It computes NLO cross sections incl...
متن کاملStudy on the low mass Drell-Yan production at the CERN LHC within the dipole formalism
The cross sections for producing lepton pairs by the Drell-Yan (DY) process have been proven to still fulfill the factorization property and are finite to first order in perturbation theory at sufficiently large transverse momenta, pT . On the other hand, there is an extensive program of research treating the low-pT region as the conventional factorization approaches give divergent results at p...
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...
