• 120 GeV proton beam (E866: 800 GeV) – cross section scales as 1/s: 7x statistics – background scales as s: 7x luminosity �50x statistics • Systematic uncertainties ~1% E906 Drell-Yan What happens at high x?
Other Physics to be Probed with Drell-Yan Partonic energy loss in nuclei • Beam quark lose energy as it penetrates nucleus � shift in observed parton momentum fraction �measure energy loss by using different size nuclei � establish a baseline for energy loss expected in heavy ion collision
