Abstract

The production of charmed particles by 340 GeV/c momentum Σ^- was studied in the hyperon beam experiment WA89 at the CERN-SPS, using the Ω-spectrometer. In two data-taking periods in 1993 and 1994 an integrated luminosity of 1600 μb^-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, D̄, D_s^- and Λ_c⁺ were determined in the region x_F > 0. Assuming an A¹ dependence of the cross section on the nucleon number, we calculate a total cc̄ production cross section of σcc̄(x_F > 0) = 5.3 ± 0.4 (stat) ± 1.0 (syst) + 1.0 (Ξ_c) μb per nucleon. The last term is an upper limit on the unknown contribution from charmed-strange baryon production.

In two data-taking periods in 1993 and 1994 an integrated luminosity of 1600 μb-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, D̄, Ds- and Λc+ were determined in the region xF > 0. Assuming an A1 dependence of the cross section on the nucleon number, we calculate a total cc̄ production cross section of σcc̄(xF > 0) = 5.3 ± 0.4 (stat) ± 1.0 (syst) + 1.0 (Ξc) μb per nucleon. The last term is an upper limit on the unknown contribution from charmed-strange baryon production.
