Abstract
We report on D*+/- production in interactions between 350 GeV/c pi(-) parti cles and nuclei. Reconstruction of the decay D*+ --> D-0 pi(+) and charge c onjugate, with D-0 identified via its decays to K(-)pi(+) and K(-)pi(-)pi()pi(+), has allowed isolation of a sample of 612 +/- 28 D*+/- mesons, produ ced at positive x(F). Assuming a linear A-dependence, the measured forward cross-sections per nucleon are 1.41 +/- 0.15 mu b for D*+ and 1.90 +/- 0.19 mu b for D*-. We present measurements of differential cross-sections with respect to x(F) and P-t(2), and compare data for D*+/- (vector-meson) produ ction with data for production of charmed pseudoscalar mesons.
