Inclusive Studies of Short-Range Correlations: Overview and New Results

Abstract: We present an overview of Short-Range Correlations (SRC) studies using the inclusive measurement of the electron scattering off nuclei. A brief introduction of the origin of the SRC is given, followed by the survey of the two-nucleon SRC (2N-SRC) study and its interesting connection to the EMC effect. A discussion of the three-nucleon SRC study (3N-SRC) measured by the Jefferson Lab's Hall B and Hall C experiments which showed contradictory results is given and, most importantly, we report a new result from the Hall A E08-014 experiment which was dedicated on studying 3N-SRC. Our high precision 4He/3He cross section ratios at the x > 2 region do not show a 3N-SRC plateau as predicted by the naive SRC model. To further investigate the 3N-SRC as well as the Isospin effect of the SRC, we have designed several approved experiments in Hall A and in Hall C, including the Tritium experiments using the mirror nuclei (3H and 3He) which are currently running in Hall A.
