EMC effect in light mirror nuclei from MARATHON

The EMC effect was first discovered in the 1980s by the European Muon Collaboration. Their measurement of the Fe to D Ratio showed a difference from unity. This difference was defined as the EMC effect. Many experiments have been conducted to measure the EMC effect for different nuclei, at different values of momentum transfer, and many other independent attributes. Jefferson Lab hosted the MARATHON (MeAsurement of the F22 / F2p, d/u RAtios and A=3 EMC Effect in Deep Inelastic Electron Scattering Off the Tritium and Helium MirrOr Nuclei) in the spring of 2018. One of the goals of the MARATHON experiment is to examine the isospin dependence of the EMC effect through measurements on the helium 3 and tritium mirror nuclei. The MARATHON experiment is the first experiment to study the EMC effect in these two mirror systems. The preliminary results of the EMC effect for Tritium will be presented.
