Yields of heavy quarks at high energies
The relative yields of с and b quarks at energies 4s £ 0.5 TeV are studied in the framework of the phenomenology of semihard processes. Absorption corrections must slow the growth of the oquark production cross section. Consequently, the b-quark production cross sections determined from the data on the yields of muons or J/ψ mesons are larger than the parton model predictions used to analyze the experimental results.
