New hints to the cause of the EMC effect
Deep-inelastic scattering cross section ratios plotted as a function of Bjorken x show that quark structure in nuclei is different than in free nucleons. Recent EMC type data from Jefferson Lab's Hall C show that the slope in the 0.3 < x < 0.7 region scales as the local nuclear density and not the average nuclear density. This result led to the comparison between x > 1 short-range correlation plateaus and the magnitude of the EMC effect slope. A clear linear relation between the two effects has now been shown. In this paper, the EMC effect, the short-range correlation plateaus and a possible reason for a relationship between the two is discussed.
