Heavy quark yields at high energies

Abstract

It is shown that the absorption correction due to gluon rescattering changes drastically the value of the cross section for heavy quark production at s ⪆0.5 TeV and also the ratio of c and b cross sections. The cross section for b-quark production, estimated from the data on muon and J/ψ production should be increased by a factor of about 2–2.5 at Fermilab-Tevatron energies.
