Probing u-bar/d-bar Asymmetry in the Proton via Quarkonium Production

Abstract
The sensitivity of proton-induced $J/Ï$ and $Î¥$ production to the possible $\bar u/\bar d$ asymmetry in the nucleon is studied. The ratio of the quarkonium production cross sections at large $x_F$ on hydrogen over deuterium targets, $Ï(p+p) / Ï(p+d)$, is shown to be sensitive to this asymmetry. Predictions of various theoretical models for this ratio are presented.
