Abstract

It has been proposed that the large cross sections for prompt ψ, ψ′, and pp̄ production at the Fermilab Tevatron pp collider can be explained by a dominant color-octet term in the fragmentation function for a gluon to split into quarkonium. We show that this mechanism makes testable predictions for double-quarkonium ψψ, ψψ′, ψXc, ψY and ψXb production, as well as for Wψ production, using color-octet matrix elements previously determined from charmonium production data. The ψψ signal would already be measurable at the Tevatron, while the ψXc and Wψ signals would be on the edge of present detectability.
