The production of J/ψ at large transverse momenta (p ⊥ > M J/ψ ) in pp collisions is considered by including the mechanism of fragmentation. Both contributions of fragmentation to J/ψ and of fragmentation to χ states followed by radiative decay to J/ψ 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.

“…In the last decade hadron-jet physics has been intensively studied in e + e − , hadron-hadron and ep scattering processes (for reviews see e.g. [3,4,5,6,7,8,9,10,11,12]). It will certainly remain one of the main topics for investigation at the e + e − , pp and ep colliders of the future.…”

In this review we discuss the analytical perturbative approach, based on perturbative QCD and local parton hadron duality (LPHD), and its application to multiparticle production in jets in the semisoft region. Analytical formulae are presented for various observables within the accuracy of the modified leading logarithmic approximation (MLLA), i.e. with terms of relative order [Formula: see text] taken into account systematically, and in some cases with even higher accuracy. These predictions are confronted with existing experimental data. Many details of the perturbative approach to multiple hadroproduction have been consolidated in recent years, and the overall picture is remarkably healthy. The prospects of future studies of the semisoft jet physics are also discussed.

“…These color coherence studies provide several important tests of QCD [4,5] and of the way in which QCD is im~lemented in the current theoretical calculations. The measurement of emission patterns for gluon radiation provides tests of perturbative QCD beyond the leading order in perturbation theory.…”
