Аннотация доклада:
The results of analysis SERP-E-184 experiment [1] data, obtained with 70 GeV proton beam irradiation of active target with carbon, silicon and lead plates are presented. For 3-prongs charged charmed mesons decays, event selection criteria were developed and detection efficiency was cal- culated with detailed simulation using FRITIOF7.02 and GEANT3.21 programs. Signals of decays were found and charm production inclusive cross sections estimated at near threshold energy. The lifetimes and A- dependence of cross section were measured. Yields of D mesons and their ratios in comparison with data of other experiments and theoretical pre- dictions are presented.
