EMC effect of tritium and helium-3 from the JLab MARATHON experiment

Abrams, D. (avtor), Mihovilovič, Miha (avtor), Širca, Simon (avtor)

Measurements of the EMC effect in the tritium and helium-3 mirror nuclei are reported. The data were obtained by the MARATHON Jefferson Lab experiment, which performed deep inelastic electron scattering from deuterium and the three-body nuclei, using a cryogenic gas target system and the high resolution spectrometers of the Hall A Facility of the Lab. The data cover the Bjorken x range from 0.20 to 0.83, corresponding to a squared four-momentum transfer Q$^2$ range from 2.7 to 11.9  (GeV/c)$^2$, and to an invariant mass W of the final hadronic state greater than 1.84  GeV/c$^2$. The tritium EMC effect measurement is the first of its kind. The MARATHON experimental results are compared to results from previous measurements by DESY-HERMES and JLab–Hall C experiments, as well as with few-body theoretical predictions.
