<p style="font-family:Times New Roman,serif;margin:0 0 8pt 0;line-height:107%"><span style="font-size:14pt">The Fermilab E906/SeaQuest is an experiment aimed at studying the anti-quark distributions of nucleons and nuclei. The experiment uses a 120 GeV/c proton
beam extracted from the Main Injector at Fermilab to collide with various solid and cryogenic targets to study a variety of physics topics. The experiment takes advantage of the Drell-Yan process in order to probe specifically the high-x anti-quark distributions
of the target nucleus. <span style="color:#222222;background-color:white">Comparison of Drell-Yan cross-section ratios of liquid hydrogen and deuterium allows SeaQuest to probe the dbar(x)/ubar(x) ratio up to a region of ~0.45 in Bjorken-x which is crucial
for non-perturbative models that are aimed at explaining the origin of the nucleon sea. The experiment has also taken data on carbon, iron and tungsten to study nuclear dependence of Drell-Yan dimuons, parton energy loss in cold nuclear matter and more. </span>Recent
results on anti-quark flavor asymmetry published in Nature and other ongoing analysis efforts will be highlighted in this talk. </span></p>
