The SeaQuest Experiment: Anti-Quark Flavor Asymmetry in the Nucleon,

Nuclear Dependence of Anti-Quarks in Nuclei and more!



Abstract:



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. 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. Recent results on anti-quark flavor asymmetry published in Nature and other ongoing analysis efforts will be highlighted in this talk.
