Detection of charged $D^\pm$ -mesons production in pA-interactions at 70 GeV with SVD-2 setup
Protvino, 2013. – p. 18, figs. 16, refs.: 14


The results of analysis for E-184 experiment data obtained with 70 GeV proton beam irradiation of active target with carbon, silicon and lead plates are presented. For three-prongs charged charmed mesons decays, event selection criteria were developed and detection efficiency was calculated with detailed modeling using FRITIOF7.02 and GEANT3.21 programs. Signal of decays was obtained and charm production inclusive cross sections were 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 predictions are presented.
