New Results on Three-Nucleon Short-Range Correlations (1810.01950v1)

Abstract: The recent progress in studies of two-nucleon~(2N) short-range correlations~(SRCs) are reviewed with the main emphasize given to the observation of the strong dominance of proton-neutron~(pn) SRCs in nuclei as compared to proton-proton and neutron-neutron SRCs. Based on the pn SRC dominance a specific prediction is made for the dynamical structure of 3N- SRCs for inclusive $A(e,e^\prime)X$ reactions, according to which the 3N- SRCs are generated through the sequence of two short range $pn$ interactions. This allowed us to predict that the height of the plateau in the ratios of inclusive eA cross sections to that of $^3He$ in the 3N-SRC region is related to the height of the plateau in the 2N-SRC region by a quadratic relation. The analysis of the available experimental data supports validity of such a relation.
