Analysis of Dilution Factor in Drell Yan and J/psi Production*

With the use of modern parton level cross-section generators, we can analyze the contributions from unmeasured cross-sections from these various materials to find the degree of dilution and the corresponding kinematic sensitivity. Data provided by earlier Drell-Yan experiments is used to fine-tune the distributions in the phase-space of interest and set the simulation input parameters. In addition, the SpinQuest experiment will also measure the Transverse Single Spin Asymmetry for J/psi production. In this presentation, I will talk about the projection of the dilution factor for both Drell-Yan and J/psi production and the expected impact on the overall systematic error in the SpinQuest experiment.
