Results published in 1983 by the European Muon Collaboration (EMC) at CERN suggested that a nucleon's partonic structure is modified when multiple nucleons are bound together in the nuclear environment. This phenomenon, now known as the EMC Effect, came as a surprise due to the relatively small energies involved in nucleon-nucleon interactions when compared to the energies present in DIS interactions. The EMC Effect has been the subject of a significant amount of theoretical and experimental effort over the past forty years to determine its underlying cause. Despite this effort, the driving mechanism behind the EMC Effect has yet to be determined.

To help solve this decades-old puzzle, experiment E12-10-008 was conducted at Jefferson Lab. Data was collected from Fall 2022 through Spring 2023, utilizing the high luminosity 12 GeV electron beam of CEBAF to probe the partonic structure of the different nuclei. In this talk, I will give an overview of the EMC Effect, highlight the key physics goals of experiment E12-10-008, and present preliminary results from our analysis.
