Testing the EMC-SRC Hypothesis with the LAD Experiment
ORAL
Abstract
The EMC effect, the observation that Deep Inelastic Scattering (DIS) from nuclei differs significantly from that on free nucleons, has puzzled nuclear physicists for nearly forty years. A potential cause for this phenomenon is short-range correlations between nucleons within a nucleus, which can be directly tested using the technique of recoil tagging. The upcoming LAD experiment in Jefferson Lab Hall C will measure backwards recoiling spectator protons in coincidence with DIS electrons from a deuterium target, and will serve as a complement to the BAND experiment. The eponymous Large Acceptance Detector consists of three walls of plastic scintillator, which will determine proton momenta through a combination of timing and energy loss measurements. High-resolution GEM detectors will help provide crucial background suppression.I will present the current status of the preparations for LAD and showcase how BAND and LAD can definitively test the SRC-EMC hypothesis.
