Description
The SeaQuest experiment at Fermilab continues a series of Drell-Yan measurements to explore the antiquark content of the nucleon and to study the modifications to nucleon structure when the nucleon is embedded into a nuclei. To extend existing measurements to larger values of Bjorken-x, a 120 GeV proton beam extracted from Fermilab’s Main Injector is used, resulting in 50 times more luminosity than previous experiments and enabling access to values of x up to 0.9. The key physics goals of the SeaQuest collaboration include the investigation of the dramatic dbar(x)/ubar(x) flavor asymmetry in the nucleon sea and its behavior at high x as well as the study of the EMC effect in Drell-Yan scattering and the unexpected absence of any antiquark excess in existing data. After a short introduction to the physics program of the SeaQuest experiment, I will present the status report on the ongoing data taking and analysis and possible updates to the SeaQuest experiment with polarized target and beam.
