Abstract
The production of charmed particles by 340 GeV/c momentum - was studied in the hyperon beam experiment WA89 at the CERN-SPS, using the -spectrometer. In two data-taking periods in 1993 and 1994 an integrated luminosity of 1600 b-1 on copper and carbon targets was recorded. From the reconstruction of 930 ± 90 charm particle decays in 10 decay channels production cross sections for D, D, Ds- and c+ were determined in the region xF > 0. Assuming an A1 dependence of the cross section on the nucleon number, we calculate a total cc production cross section of cc(xF > 0) = 5.3 ± 0.4 (stat) ± 1.0 (syst) + 1.0 (c) b per nucleon. The last term is an upper limit on the unknown contribution from charmed-strange baryon production.
