"Measuring Local Modification of Nucleon Structure"

Cameron Cotton , UVA
[Host: Dustin Keller]

In 1983, results published by the European Muon Collaboration (EMC) at CERN suggested that the quark structure of nucleons are modified when they are bound together in the nuclear environment. This modification, now called the EMC Effect, was largely unexpected and has been the subject of a significant amount of theoretical and experimental effort over the past 40 years to determine its underlying cause. Despite this effort, the exact mechanism that causes the EMC Effect has continued to elude physicists.

Experiment E12-10-008 at Jefferson Lab aims to shine a bright new light on this 40-year-old problem. Having collected data from September 2022 through February 2023, this experiment utilized the high luminosity 12 GeV electron beam of CEBAF to probe, with high precision, the quark structure of nearly 20 different nuclei. Data from this experiment will provide a significant contribution to the global set of EMC Effect data, producing the first measurements of the EMC Effect in many new nuclei and reducing uncertainty on previously studied nuclei. In this seminar, an overview of the EMC Effect will be given and the physics motivation of experiment E12-10-008 will be presented.
