Description
The modification of bound nucleon structure function in nuclei, known as the EMC Effect, was first observed over 40 years ago through Deep Inelastic Scattering (DIS) ratios comparing deuterium to other nuclei. Despite extensive study, the underlying mechanism behind this effect remains unresolved. A prominent hypothesis attributes the EMC Effect primarily to the modification of high-virtuality nucleons within Short Range Correlated (SRC) pairs, while mean-field nucleons remain largely unaltered.
The LAD experiment, conducted in Hall C of Jefferson Lab, aims to test this hypothesis using spectator-tagged DIS. The experimental setup includes a large acceptance detector (LAD) comprised of GEMs, and scintillator bars, which complements Hall C’s existing high resolution spectrometers. By tagging backward spectator protons, LAD will provide detailed insights into the initial state of the deuteron and its associated quark structure.
This presentation will outline the current status of the LAD experiment and discuss its connection to other ongoing experimental and theoretical advancements.
