Abstract
The E906/SeaQuest experiment at Fermilab will use the 120 GeV/c proton beam extracted from the Main Injector to measure the light antiquark flavor asymmetry, ¯ d/¯u, in the nucleon sea, and how it is altered in nuclei. It will provide direct input to the parton distribution fits, and provide a better understanding on the physical mechanism which generates the sea of the proton. The experiment will start in the fall of 2011 and run until the end of 2014. After completion of the SeaQuest experiment, the spectrometer will be available for a polarized Drell-Yan program, either with a polarized beam or a polarized target. The first in a long list of possible experiments at the Main Injector is a polarized Drell-Yan experiment, motivated by a fundamental prediction of QCD that postulates a sign change in the Sivers function measured in Drell-Yan as compared to deep inelastic scattering.
