Properties of Neutral Charmed Mesons in pA-interactions at 70 GeV
Protvino, 2010. – p. 11, figs. 9, tables 3, refs.: 11.


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. When two-prongs neutral charmed mesons decays signal has been obtained and charm production cross section estimated at near threshold energy (σ(cĉ) = 7.1 ± 2.4 (stat.) ± 1.4 (syst.) (mkb/nucleon)), some properties of D0 and Ď0 were studied, in particular: A-dependence of cross section, kinematical distributions dσ/dpt2 and dσ/dxf, the dependence of α parameter versus xf, pt2 and plab. Experimental results are compared to the predictions of FRITIOF7.02 program.
