Abstract

Jefferson Lab has had great success using high-energy probes to significantly advance our understanding of energetic, high-density components of nuclear structure. Studies of high-momentum nucleons associated with short-range correlations (SRCs) have mapped out the strength and isospin dependence of these energetic components in nuclei, providing new insight into their connection to nuclear structure and the N-N interaction. Studies of nuclear parton distributions and the EMC effect have also shown unexpected behavior in light nuclei, and raised questions about a correlation or common origin for the EMC effect and short-range correlations. It also suggests a mechanism for a flavor dependence in the EMC effect for non-isoscalar nuclei, which could have significant impact on a range of other experiments at Jefferson Lab and in high-energy scattering and collider experiments around the world. ~ I will highlight key insights gained from the 6 GeV program at Jefferson Lab, discuss the potential impact on measurements of neutrino and electron scattering from nuclei and A-A, and briefly present future experiments aimed at further illuminating these exotic components of nuclear structure.
