Hadron Structure from DIS, SIDIS, and DY Processes
- Lamiaa El Fassi (Mississippi State U.)
The partonic structure of the proton is of great interest in hadron physics. Particularly the distribution of antiquarks has gained a lot of attention due to its unique sensitivity to the dynamics of the strong force (i.e. QCD).
SeaQuest at Fermilab is a fixed-target experiment to measure the Drell-Yan process in proton+proton and proton+deuteron scattering, using the 120-GeV proton beam...
Recent analysis of unpolarzed data for Drell-Yan and SIDIS show new light of the structure of nucleai.We perform an anlysis on these data, at small transverse momentum and using the TMD factorization theorem. I will show recent progresses in this analysis which include W-boson analysis, the impact of PDF and flavor dependence.
COMPASS is a fixed target experiment in the North Area of CERN. One of the primary goals of its broad physics program is to study the transverse momentum dependent (TMD) parton distribution functions (PDFs) that describe the spin structure of nucleons. To extract observables related to TMD PDFs, COMPASS uses both Semi-Inclusive Deep Inelastic Scattering (SIDIS) and the Drell-Yan (DY) process....
The E1039/SpinQuest experiment is a transversely polarized fixed target experiment at Fermi National Accelerator Laboratory aiming to explore the sea quark and gluon Sivers functions via the measurement of the transverse single spin asymmetry (TSSA) for a number of physics processes including J/Psi, Psi’ and Drell-Yan production. The experiment employs a 120-GeV extracted proton beam colliding...
We perform the global analysis of polarized Semi-Inclusive Deep Inelastic Scattering (SIDIS), pion-induced polarized Drell-Yan (DY), and W+-/Z boson production data and extract the Sivers function for u, d, s, and for sea-quarks. We use the framework of transverse momentum dependent factorization at N3LO accuracy. The Qiu-Sterman function is determined in a model-independent way from the...
