Charge Asymmetries for D, Ds and Lambdac Production in Sigma- - Nucleus Interactions at 340 GeV/c
The WA89 Collaboration, M. I. Adamovich et al
Abstract
CERN experiment WA89 has studied charmed particles produced by a 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- and Dp, Ds and Ds+ and Lambdac and Antilambdac are observed. The results are compared with pion beam data and with theoretical calculations.
