Calculating the Q-Square(perpendicular)-Dependence in Drell-Yan Processes
In this thesis we calculate the Drell-Yan cross-section for the production of massive muon pairs at moderate values of q(,(PERP))('2). We do this in several theories, including the important case of Quantum Chromodynamics. By looking at another field theory which is simpler than QCD, we give …

Nuclear dependence of proton-induced Drell-Yan dimuon production at 120 GeV at SeaQuest
… measurement of the atomic mass (A) dependence of Drell-Yan (p + A → μ+μ− + X) dimuons produced by 120 GeV protons is presented here. The data was taken by the SeaQuest experiment at Fermilab using a proton beam extracted from its Main Injector. Over 61,000 dimuon pairs were recorded with invariant …

Measurement of the Drell--Yan differential cross section with the CMS detector at the LHC
… of operation. Measurements of the differential Drell–Yan cross section in the dimuon and dielectron channels covering the dilepton mass range of 15 to 2000\GeV and absolute dilepton rapidity from 0 to~2.4 are presented. The Drell–Yan cross section in proton-proton collisions depends on empirical …

A measurement of the inclusive differential Drell-Yan cross-section with dimuons at sqrt.s = 1.8 TeV
The inclusive differential Drell-Yan cross section is measured from the analysis of $\bar{p}p\to\gamma\to\mu\sp+\mu\sp-X$ events at a center-of-mass energy of $\sqrt{s}$ = 1.8 TeV at the Fermilab Tevatron collider. The dimuon events are accepted in the central pseudorapidity region of …

Transverse momentum dependent nucleon structure from pions impinged on a transversely polarized proton target
… and theorized to change signs between the Drell-Yan process and Semi-Inclusive Deep Inelastic Scattering (SIDIS). The COMPASS spectrometer is unique in that it has the ability to measure the products from a polarized target and also because the beam can be modified to measure the SIDIS and …

The readout system of the HERA-B Inner Tracker and prospects of HERA-B in the field of Drell-Yan physics
… of HERA-B to contribute to the field of Drell-Yan physics are evaluated, where significant deviations from the predictions of perturbative QCD were observed. Starting from an analysis of the di-muon triggered data of the run period 2000, the expected number of high-mass muon pairs …

Measurement of high-mass dimuon production for p+p and p+d collisions with 120 GeV proton beam at Fermilab
… in nucleons and nuclei. In particular, the Drell-Yan cross-section ratios for liquid deuterium over hydrogen will allow the measurement of sea quark asymmetry, $\bar{d}/\bar{u}$, for Bjorken-{\it x} ranging from 0.1 to 0.45, extending the measurements of the previous experiment NuSea/E866. …

Measurement Of Angular Coefficients Of Drell-Yan E(+) E(-) Pairs In Ppbar Collisions At Square Root Of Center Of Mass Energy Of 1.96 Tev.
In this paper we present the status of the measurement of angular distributions of final state electrons in ppbar → γ*/Z → e+ e− + X events produced in the Z boson mass region at square root of center of mass energy of 1.96 TeV at the Tevatron. For this analysis, we have used the Run IIb2 dataset …

Forward change distributions associated with hadronically produced J/psi particles

The measured forward charge becomes more negative as the X, of the J/psi increases although it is consistent with being flat as a function …
