Registration of Neutral Charmed Mesons Production and Their Decays in pA-Interactions at 70 GeV with SVD-2 Setup
Protvino, 2009. – p. 15, figs: 14, tables 3, refs.: 17


The results of data handling for E-184 experiment are presented received with 70 GeV proton beam irradiation of active target with carbon, silicon and lead plates. Two-prongs neutral charmed D0 and ¨D0 -mesons decays signal are obtained. Signal/background ratio is (51±17)/(38±13). Efficiency of registration for mesons are defined and evaluation for charm production cross section at near threshold energy are presented: \sigma(cč)=7.1 ±(stat.) ± 1.4(syst.) (mkb/nucleon).
