Short Range Correlations and the EMC Effect
Journal Article
·
· Phys. Rev. Lett.
This Letter shows quantitatively that the magnitude of the EMC effect measured in electron deep inelastic scattering at intermediate xB, 0.35≤xB≤0.7, is linearly related to the short range correlation (SRC) scale factor obtained from electron inclusive scattering at xB≥1. The observed phenomenological relationship is used to extract the ratio of the deuteron to the free pn pair cross sections and F2n/F2p, the ratio of the free neutron to free proton structure functions. We speculate that the observed correlation is because both the EMC effect and SRC are dominated by the high virtuality (high momentum) nucleons in the nucleus.
