Title Deep inelastic scattering from A = 3 nuclei: Nucleon structure and the EMC effect
Abstract The MARATHON experiment ran at Jefferson Laboratory in 2018, measuring deep inelastic scattering of 10.6 GeV electrons from the proton (p), deuterium (D), tritium (3H), and helium-3 (3He). MARATHON's experimental observables are cross section ratios, most notably 3H/3He. This ratio of mirror nuclei is used for a novel extraction of the nucleon structure function ratio Fn 2 /Fp 2 with minimal nuclear corrections. Determining leading-order Fn 2 /Fp 2 at high x provides important constrains on the ratio of nucleon valence quark distributions d/u. The ratios 3H/D and 3He/D allow a determination of the EMC effect in the lightest nuclei sensitive to possible isospin dependence of nuclear effects. Lastly, the D/p ratio allows a comparison of the MARATHON experiment to SLAC measurements, and provides data to which the A = 3 ratios can be renormalized. The MARATHON results provide new constraints on d/u. Additionally, the results emphasize the importance of higher-order effects in extracting Fn
