Double Asymptotic Scaling in Drell-Yan Processes
Double scaling may be observed in the Drell-Yan process at the Tevatron and in the ALICE detector at the Large Hadron Collider in a window of masses. In the double scaling limit of the cross section, the higher order QCD corrections are quite large, and are driven by the rise in gluon densities in the double scaling regime. The naive parton model cannot be valid even at asymptotic energies in t...
متن کاملDouble–spin Transverse Asymmetries in Drell–yan Processes
We calculate the double–spin transverse asymmetries for the Drell–Yan lepton pair production in pp and p̄p collisions. We assume the transverse and the longitudinal polarization densities to be equal at a very small scale, as it is suggested by confinement model results. Using a global fit for the longitudinal distributions, we find transverse asymmetries of order of 10 at most, in the accessibl...
متن کاملDrell - Yan Scaling in Semi - Inclusive Electroproduction ”
The scaling behavior of deep inelastic single-particle inclusive electroproduction (or neutrino production) expected from the parton model has been given by Drell and Yan as v 3 g&2 when the observed hadron has a finite fraction of the virtual photon’s laboratory momentum. Although Drell and Yan give the correct scaling behavior with their choice of variables, we show that with variables more a...
متن کاملElectroweak & QCD corrections to Drell Yan processes
The relevance of single-W and single-Z production processes at hadron colliders is well known: in the present paper the status of theoretical calculations of Drell-Yan processes is summarized and some results on the combination of electroweak and QCD corrections to a sample of observ-ables of the process pp → W ± → µ ± + X at the LHC are discussed. The phenomenological analysis shows that a hig...
متن کاملDrell-Yan-like processes and duality
We calculate the gauge invariant Drell-Yan-like hadron tensors. In connection with new COMPASS results, we predict the new single spin asymmetry which probes gluon poles together with chiral-odd and time-odd functions. The relevant pion production as a particular case of Drell-Yan-like process has been discussed. For the meson-induced Drell-Yan process, we model an analog of the twist three dis...
