Registration of Neutral Charmed Mesons Production and their Decays in pA-Interactions AT 70 GeV with SVD-2 Setup.
SVD-2 Collaboration

The results of data handling for SERP-E-184 experiment obtained with 70 GeV proton beam irradiation of active target with carbon, silicon and lead plates are presented. Two-prongs neutral charmed D⁰ and -mesons decays were selected. Signal / background ratio is (51±17) / (38±13). Registration efficiency for mesons was defined and evaluation for charm production cross section at threshold energy is presented: = 7.1±2.4(stat.)±1.4(syst.) (µb/nucleon).
Key words: pA-interactions, charm production, cross section, simulation, data handling
