| Abstract | A systematic search for superfragments (charmed nuclei) has been performed in 22 200 neutrinoâ"emulsion interactions obtained with the CHORUS experiment making use of automatic off-line image analysis. The absence of candidates provides an upper limit for the superfragment production rate of 1:9 _ 10_4 (90% C.L.) relative to neutrino charged-current interactions at an average neutrino energy of 27 GeV. In the same analysis 28 hyperfragment decays were found. For the first time, a production rate of hyperfragments in neutrinoâ"emulsion interactions was obtained. The value of the hyperfragment production rate relative to the neutrino charged-current cross-section was found to be (2:0 _ 0:4 (stat) _ 0:3 (syst)) _ 10_3. |
