Light-front holography model of the EMC effect

A new two-component model of the EMC effect based on light-front holographic QCD (LFHQCD) is presented. The model suggests the EMC effect is the result of the nuclear potential breaking SU(6) symmetry. The model separates the F₂^A nuclear structure function into two parts: a free contribution, involving the addition of proton and neutron structure functions, weighted by the number of protons and neutrons respectively, and a nuclear/medium modified contribution that involves a nucleus-independent universal function. Further, the model displays a correlation between the size of the EMC effect and the SRC pair density a₂, extracted from kinematic plateaus at around x > 1 in inclusive quasielastic (QE) scattering.
