MEASUREMENT OF THE EMC EFFECT OF THE TRITIUM NUCLEUS AT JEFFERSON LAB

Experiment E12-10-103 (MARATHON) was conducted in the Hall A Facility of JLab in the winter/spring of 2018 during the initial phase of the 12 GeV energy upgrade of the Lab. One goal of the experiment was the first measurement of the EMC effect of 3H. Four sealed gas targets were used during the experiment, 1H, 2H, 3H, and 3He. All measurements were in the deep inelastic scattering kinematical regime with large Q2 and W2, which are the four-momentum transfer squared and invariant mass squared of the final hadronic state in the inelastic scattering interaction, respectively. The range of Q2 and W2 were 3 < Q2 <12 (GeV/c)2 and 3.2 < W2 < 12.3 GeV/c2, respectively. The measurements spanned a wide range of the Bjorken variable x, between 0.19 and 0.83, where x = Q2/2M(E-E') is the momentum fraction carried by the struck quark in the interaction, with M being the nucleon mass. Knowledge of the EMC effect of light nuclei, such as 3H, will provide an opportunity to better understand the origin of the EMC effect.
