Experiment E866, conducted at the Fermi National Accelerator Laboratory, is a high statistics experiment to measure {anti u}(x)/{anti d}(x) in the proton over a wide range of x. A review of the current evidence for {anti u}(x) {ne} {anti d}(x) in the proton is given and is followed by a short description of the spectrometer and the experimental procedures used in E866. Preliminary results are shown for the ratio of the Drell-Yan cross sections {sigma}{sup pd}/2{sigma}{sup pp}. The preliminary results confirm the conclusions of both the NMC and NA51 collaborations that there is an {anti u}/{anti d}(x) asymmetry in the ...

Experiment E866, conducted at the Fermi National Accelerator Laboratory, is a high statistics experiment to measure {anti u}(x)/{anti d}(x) in the proton over a wide range of x. A review of the current evidence for {anti u}(x) {ne} {anti d}(x) in the proton is given and is followed by a short description of the spectrometer and the experimental procedures used in E866. Preliminary results are shown for the ratio of the Drell-Yan cross sections {sigma}{sup pd}/2{sigma}{sup pp}. The preliminary results confirm the conclusions of both the NMC and NA51 collaborations that there is an {anti u}/{anti d}(x) asymmetry in the proton sea.
