Description

Since the discovery of the EMC Effect nearly 40 years ago, there has been significant theoretical and experimental effort dedicated to understanding its underlying cause. However, to this day, the EMC Effect remains one of the great unsolved mysteries in nuclear and particle physics. Questions such as whether the EMC Effect implies that nucleon form factors are modified in nuclei or if the effect can even be explained within the framework of the conventional nucleon-meson treatment of nuclear physics highlight the importance of understanding this phenomenon.

I will provide some background on the EMC Effect and discuss its connection with Short Range Correlations (SRCs). I will then focus on how, by utilizing the upgraded 12 GeV beam at Jefferson Lab (JLab), we will make a significant contribution to the global set of EMC Effect data, improving on existing JLab measurements. This includes extending extraction of EMC ratios out to larger Q2 and Bjorken x, as well as making additional measurements of many new nuclei, especially light nuclei that are well understood and amenable to comparison with exacting theoretical calculations.
