High Energy proton-proton collisions at the LHC are capable of producing many electroweak bosons (W/Z) at high rapidity. Measurements on properties of these particles are essential standard candles used for detector and luminosity calibration. The collision of heavy nuclei can show significant modifications to electroweak boson cross sections. I will present an analysis of electroweak boson production in lead-lead collisions at the LHC using the nCTEQ nuclear Parton Distribution Functions (PDFs). Transverse Momentum Dependent PDFs (TMD PDFs) will be discussed along with methods for extracting these PDFs from data.
