Hadroproduction of heavy flavors

The subject of this review, as one can gather from the title, is the current state of knowledge (or ignorance) of heavy quark production, particularly charm, by hadron beams. The only report of B mesons in a hadron experiment is that of the WA75 collaboration. The author comes back to that experiment because of its interesting implications for B lifetimes, but the rest of the paper deals exclusively with charm production. Charm hadroproduction, like all Gaul, can be divided into three parts: total cross section, pT, and xF dependence. The only other question that arises concerns the species that have been observed. Of the mesons, the charged and neutral D and D* have certainly been seen. The F has probably been found, but the evidence is sketchy and somewhat contradictory. The Λc and the A+ baryons appear secure, while the T degree is on much shakier ground
