On the total charm production cross section in hadronic interactions at high energies root s > 1.8 TeV

摘要

Results of processing experimental data on charm production in hadron-hadron interactions are presented. The paper discusses three channels of charm production: (1) single diffractive dissociation, (2) double diffractive dissociation, (3) hard processes. The analysis of single diffractive dissociation is carried out within the frame of the phenomenological model of diffractive production and quark statistics based on the additive quark model (AQM). In a low-energy region root s = 20-40 GeV, the cross sections sigma(pN -> c
