Abstract
In this talk the author shows the results of a fit of the NRQCD matrix elements to the CDF data for direct J/{psi} production, by including the radiative corrections to the g g {r_arrow} {sup 3} S {sub 1}{sup [1]} channel and the effect of the k{sub T}-smearing. Furthermore he performs the NLO NRQCD analysis of J/{psi} production in fixed-target proton-nucleon collisions and he fits the colour-octet matrix elements to the available experimental data. The results are compared to the Tevatron ones.
