Charge asymmetries for D, Ds and [lambda]c production in [sigma]- -nuleus interactions at 340 GeV/c
CERN experiment WA89 has studied charmed particles produced by a Σ−Σ−\Sigma^- beam at 340 GeV/c on nuclear targets. Production of particles which have light quarks in common with the beam is compared to production of those which do not. Considerable production asymmetries between D−D−\mathrm{D}^- an...

| Summary: | CERN experiment WA89 has studied charmed particles produced by a Σ−Σ−\Sigma^- beam at 340 GeV/c on nuclear targets. Production of particles which have light quarks in common with the beam is compared to production of those which do not. Considerable production asymmetries between D−D−\mathrm{D}^- and D+D+\mathrm{D}^+, D−sDs−\mathrm{D}_\mathrm{s}^- and D+sDs+\mathrm{D}_\mathrm{s}^+ and ΛcΛc\Lambda_\mathrm c and Λc¯Λc¯\bar{\Lambda_\mathrm c} are observed. The results are compared with pion beam data and with theoretical calculations. |
