Description
Exploring EMC-style ratios for x>1 provides critical insights into the EMC effect. Inclusive scattering from nuclei at Bjorken x>1 and high Q2 is particularly sensitive to the distribution of high-momentum quarks, often referred to as 'superfast quarks.' These quarks, which carry momentum exceeding that of a nucleon, are linked to the short-distance structure of nuclei. This region presents a promising opportunity to investigate the role of quark degrees of freedom in nuclear structure. The 12 GeV data from Jefferson Lab enables a more precise study compared to the 6 GeV data, the maximum energy achievable before the upgrade, as the higher Q2 values enhance the dominance of deep inelastic scattering (DIS) while suppressing quasi-elastic contributions
