Total charm production cross section and production asymmetries in 340 GeV/c $\Sigma^{-}$ nucleus interactions
CERN experiment WA89 uses a Sigma /sup -/ beam at 340 GeV/c to study the production of charmed particles. Based on the reconstruction of all final charm states from the full data sample of our '93 and '94 beamtimes the total $9 cc-cross section has been determined. Production of particles...

| description | CERN experiment WA89 uses a Sigma /sup -/ beam at 340 GeV/c to study the production of charmed particles. Based on the reconstruction of all final charm states from the full data sample of our '93 and '94 beamtimes the total $9 cc-cross section has been determined. Production of particles which have a light quark in common with the beam is compared to production of those which do not. Considerable production asymmetries between D/sup -/ and D/sup +/, D/sub $9 s//sup -/ and D/sub s//sup +/, and Lambda /sub c/ and Lambda /sub c/ are observed. (3 refs). |
