Hadroduction of heavy flavors

The current state of knowledge of heavy quark production, particularly charm, by hadron beams is reviewed. The state of knowledge of total cross section, p/sub T/ and x/sub F/ dependence of charm hadroproduction is given. Besides D production, production of D* is discussed. Also covered is the present evidence for hadronically produced B mesons. 28 refs., 5 figs., 3 tabs. (LEW

The performance of a uranium gas sampling calorimeter

The performance of a uranium gas sampling hadron calorimeter is described. It has been observed that the hydrogen content of the gas mixture plays an important role in defining the behaviour of this type of calorimeter. The low-energy neutrons emerging from a hadron cascade are detected much more efficiently in a hydrogenous gas; thus leakage or containment of these neutrons becomes an important feature of the calorimeter setup.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/26011/3/0000078.pd
