Charmed and bottom flavoured particle production in hadronic interactions

Abstract

In this review emphasis is put on hadroproduction of open heavy flavours and on results from fixed target experiments and hadron colliders. It should be complementary to several recent reviews which concentrate on Ec and 6 b bound states and results from ete-colliders.The atomic number dependence, the xF and PT dependence and the energy dependence of charmed particle production are discussed. Where appropriate a comparison is made with heavy flavour production in photon and neutrino interactions and in e+e-collisions. It will be shown that, contrary to a belief which was widely held until recently, the QCD parton model is not incompatible with present data. Higher-order corrections and interactions between the heavy quarks produced and the quarks in the parent hadron are likely to be important.

“…There are many measurements of the charm production cross section in low energy p + p or p + A collisions via both semi-leptonic and hadronic decays at CERN and Fermilab [11,12]. Results for the total charm cross sections (from measurements with reasonable extrapolations) are consistent with Next-to-Leading-Order (NLO) pQCD calculations.…”

Charm and bottom production: theoretical results versus experimental data

“…We remind the reader that many puzzling ISR results in pp collisions at 62 GeV remain di cult to explain (see the review in ref. [36]), in particular the large b production rates reported in ref. [30].…”

Heavy flavour production

“…[27], [28]. For an older review see [29]. Results on bottom production at fixed target are given in refs.…”

“…As one can see, experimental results on total cross sections for charm and bottom production at fixed target are in reasonable agreement with theoretical expectations. We remind the reader that many puzzling ISR results in pp collisions at 62 GeV remain difficult to explain (see the review [29]), in particular the large Λ b production rates reported in ref. [31].…”
