Description
The connection between nuclear cluster structure and modification of the nuclear quark distributions can be seen in the behavior of the EMC effect in light nuclei and in the connection between the EMC effect and the presence of short-range correlations (SRCs) in nuclei. However, it is not yet clear if this related to the high densities associated with these two-nucleon clusters or the high-momenta generated through the short-range part of the N-N interaction. In either case, this connection also suggests that that the difference in proton and neutron distributions in neutron-rich nuclei will generate a difference between the modifications of up- and down-quark distributions in nuclei. I will discuss both interpretations of the connection between SRCs and the EMC effect, their implications on the EMC effect, and plans to better understand the origins of this intriguing connection.
