Abstract
The Fermilab E866/NuSea Collaboration has measured the Drell-Yan dimuon cross sections in 800 GeV/ and collisions. This represents the first measurement of the Drell-Yan cross section in collisions over a broad kinematic region and the most extensive study to date of the Drell-Yan cross section in collisions. The results indicate that recent global parton distribution fits provide a good description of the light antiquark sea in the nucleon over the Bjorken- range , but overestimate the valence quark distributions as .
