Description
Data from the 70 GeV proton beam-dump experiment have been analysed with the aim of the detection of signal from the prompt muon antineutrino. The 'equilibrium' μ+ and μ- muons, produced in the interactions of neutrinos and antineutrinos in muon iron filter, placed in front of the detector have been registered by the IHEP-JINR Neutrino detector. The upper limit for total cross section of charm particle production at 70 GeV pN-interactions has been obtained: σcc < 4.7 μb/nucl. (90% C.L.). Results are compared with the data, received in other experiments. The anomaly high charm production cross section has not been observed near a threshold. The upper limit of the charm production cross section doesn't contradict to the theoretical calculations based on QCD. (author). 21 refs.; 6 figs.; 4 tabs
