J/psi Production via Fragmentation at the Tevatron

Abstract

The production of $\jpsi$ at large transverse momenta ($\pt > M_\jpsi$) in $p\bar{p}$ collisions is considered by including the mechanism of fragmentation. Both contributions of fragmentation to $\jpsi$ and of fragmentation to $\chi$ states followed by radiative decay to $\jpsi$ are taken into account. The latter is found to be dominant and larger than direct production. The overall theoretical estimate is shown to be nearly consistent with the experimental observation.
