Abstract
We estimate ψψ production at collider energies in the framework of perturbative QCD. TheO(α 2 s )−(α 4 s ) parton cross-sections, with the non-relativistic approximation for the heavy quark bound states, are used. This first insight into the characteristics of the kinematical distributions allows predictions on the predominance of the quark, gluon orB meson production mechanisms in particular kinematical regions.
