摘要：

The production of J/psi at large transverse momenta (pr > M(J/psi) in <p(p)over bar> collisions is considered, including the mechanism of fragmentation. Contributions of fragmentation both to production of J/psi and to production of chi states followed by radiative decay to J/psi 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.
