Duality predictions for the production of heavy quark systems in QCD (original) (raw)

Physics Letters B, 1978

Abstract

Abstract Using partonic semi-local duality ideas combined with QCD we derive absolute, parameter-free predictions for the cross sections of heavy quarkonia (J/ψ, ψ′, ′, …) production in purely hadronic collisions as well as in photoproduction proces We also discuss “open” charm (D D ) production and show how the CERN SPS beam dump measurements at √s = 27.4 GeV can be naturally reconciled with the predictions of QCD; similarly the recent ISR data are in good agreement with QCD.
