[en] A search for charmed particles produced in π^-p exclusive reactions at 19 GeV/c incident beam momentum has been carried out with the Omega spectrometer at CERN. Three million interactions were recorded with a trigger which required a forward K^- or anti p with transverse momentum greater than 0.5 GeV/c. An additional two million triggers were recorded with a forward K⁺ or proton, with no transverse momentum restriction. Analysis of the four-constraint final states K⁺K^-π^-p and K⁺K^-π⁺π^-π^-p shows no evidence for the associated production of charmed particles. The upper limits for the product of production cross sections and the two charmed particle decay branching ratios are below 100 nb for most of the channels. The experiment was sensitive over a wide range of production angles. (Auth.)
