Description
The SpinQuest experiment (E1039) at Fermilab aims to extract Sivers functions for the light sea-quarks in the range of 0.1 < xB < 0.5 through Transverse Single Spin Asymmetry (TSSA) measurements from the Drell-Yan (DY) process, using an unpolarized 120 GeV proton beam interacting with polarized fixed target of either NH3 or ND3. In addition to the DY TSSA measurements, J/ψ TSSAs will also be measured to extract the gluon Sivers function. The SpinQuest experiment will be put into a global context, considering its unique kinematic coverage, which will serve as a bridge between probing valence quarks and kinematics at future EIC experiments. The goals, as well as the importance of the measurements, will be discussed in detail.
