Description
Short-Range Correlations (SRCs) between nucleons appear to a ubiquitous feature of the structure of nuclei. While correlated nucleons are a minority (estimated to be approximately 20% of nucleons in all but light nuclei), they can have an outsized influence on a number of relevant nuclear properties such as the symmetry energy in the nuclear matter equation of state, matrix elements in double beta decay, and the modification of nucleon partonic structure by the nuclear medium. For this reason, several recent and upcoming experiments at Jefferson Lab aim to address several key open questions that will improve our understanding the structure and dynamics of SRCs. CLAS12's Run Group M recently made a high statistics measurements of SRC break-up reactions on a wide range of nuclei to address, among a myriad of questions, the possibility of three-nucleon correlations. A recent measurement in Hall D was the first use of photoproduction to study SRCs, helping to answer questions about reaction mechanisms and probe-independence. The BAND Experiment at CLAS12, currently under analysis, seeks to address the role of SRCs in the EMC Effect. These and other upcoming experiments will be reviewed.
