Study the Nucleon-Nucleon Force with Short Range Correlation Measurements

Although the nucleon-nucleon interaction have been studied intensively in the past decades, the experimental data at short distances is limited. Short Range Correlation (SRC), introduce a powerful tool to investigate the short-distance force between nucleons. The use of SRC allows to experimentally investigate the tensor and repulsive parts of the nucleon-nucleon interaction. Exclusive studies of SRC demonstrated that the nucleon-nucleon interaction at short distance is insensitive to the size of nuclei. This allows to use light nuclei in order to compare experimental and theoretical predictions. Recently we performed exclusive SRC measurements on ⁴He at Hall A in Thomas Jefferson National Accelerator Facility. The dynamics of the nucleon-nucleon interaction as a function of the nucleon initial momenta was studied. In addition, data from the CLAS detector (a roughly 4π detector) was analyzed as part of the data-mining project. Some published and preliminarily data will be shown and discussed.
