Charm-sea Contribution to High-pT ψProduction at the Fermilab Tevatron
Cong-Feng Qiao
Abstract
The direct production of J/ψ(ψ') at large transverse momentum, pT MJ/ψ, at the Fermilab Tevatron is revisited. It is found that the sea-quark initiated processes dominate in the high-pT region within the framework of color-singlet model, which is not widely realized. We think this finding is enlightening for further investigation on the charmonium production mechanism.
