Abstract: | Hadronic collisions are quite efficient in producing new quark flavours due to the large gluon content of ordinary hadrons. In particular, one may expect sizable yields of heavy quark-antiquark bound states with various spin and orbital quantum numbers. Using perturbative QCD in combination with the nonrelativistic quarkonium model we present a fairly complete and detailed picture of charmonium and bottomonium production. We compare our results on inclusiveJ/ψ and γ distributions with high energypp data and make predictions onη c and χ production. |
