Abstract

Predictions of Quantum Chromodynamics for the hadronic production of heavy flavours are reviewed, with special attention to the progress made in the last year. The contribution of flavour excitation diagrams is discussed in detail and a procedure is given which allows to cure their divergences and to stabilize their calculation. A comparison of the results with charm cross-section data is made, showing that the level and the energy behaviour of the charm cross-section are thus correctly reproduced. The observed production of diffractive Λ c is shown to be naturally understood by means of a simple recombination model. Expectations for the general features of charm production at collider energies are worked out and in particular it is shown that i) \(\sigma \left( {\bar cc} \right) \simeq \) 10 mb at the CERN p collider, which entail e/π ≈ 5 10−3 near 90°; ii) charm events should have relatively high multiplicities. Problems arising in the theoretical prediction of bottom and top particle production are outlined.
