Abstract

Charmed-meson production by 350 GeV/c pi(-) particles incident on copper and tungsten targets has been studied in the WA92 experiment, performed at the CERN Omega' spectrometer. Results obtained are reported and discussed. Reconstruction of decays from the set D-0 --> K- pi(+), D-0 --> K(-)pi(-)pi(+)pi(+), D+ --> K(-)pi(+)pi(+), D-s(+) --> phi pi() and charge conjugates has yielded a sample of 7280 +/- 108 charmed mesons, produced with chi(F) > 0, (chi(F)) = 0.18 and [p(T)(2)] = 1.86(GeV/c)(2). Assuming a relationship sigma = sigma(0)A(alpha) between the cross section, sigma, per nucleus of mass A and the nucleonic cross section, sigma(0), the alpha value found for the detected charmed particles is 0.95 +/- 0.06 +/- 0.03. Taking alpha = 1, the measured cross sections per nucleon for chi(F) > 0 production are 7.78 +/- 0.14 +/-0.52 mu b for D-0/(D) over bar(0), 3.28 +/- 0.08 +/- 0.29 mu b for D+/D- and 1.29 +/- 0.16 +/- 0.33 mu b for D-s(+)/D-s(-). Differential cross sections with respect to chi(F) and p tau(2) have been determined for the various types of charmed meson, and particle-antiparticle asymmetries have been analysed.
