Another option is to examine the EMC effect at x>1 by measuring the distribution of super-fast quarks, where a single nucleon carries more longitudinal momentum than carried by an average proton in the nucleus. While most models show extremely small nuclear effects in the deuteron in the conventional EMC effect region, many of these show much larger effects at x>1. In addition, different classes of models motivated the observation of a correlation between the EMC effect and short-range correlations give very different predictions for x>1, providing a unique sensitivity. I will review existing and recently taken data from Hall C at Jefferson Lab, as well as future measurements and the EIC and/or at an energy-upgraded Jefferson Lab, which will be able to make clean and decisive measurements providing new and unique insight into the EMC effect.
