Аннотация: The results of processing the data of the SERP-E-184 experiment that studied mechanisms of the production of charmed particles in proton-nucleus interactions at 70 GeV and their decays are presented. The data were obtained in irradiating the SVD-2 active target consisting of carbon, silicon, and lead plates with a 70-GeV proton beam. A detailed simulation based on the FRITIOF7.02 and GEANT3.21 packages made it possible to optimize event-selection criteria and to calculate the detection efficiencies for D ± mesons. After the selection of a signal from the three-body decay of charged charmed D ± mesons, the inclusive cross sections for their production at threshold energies were measured along with respective lifetimes and parameters of the A dependence of the cross sections. The yields of D mesons and their ratios are compiled in a table along with data fromother experiments and the respective theoretical predictions.
