Abstract

Fermilab E866 has performed a precise measurement of the ratio of Drell-Yan yields in 800 GeV/c pp and pd collisions, leading to determinations of d̄/ū and d̄ - ū in the proton as functions of x. The results provide valuable information regarding the origins of the d̄/ū asymmetry and the antiquark sea in the nucleon.
