Résumé : We have made the first observations of Ξ- production in pp interactions at √s=540 GeV. In a sample of 6964 non single-diffractive events we observe 17 Ξ- decays with an estimated background of less than one event. This corresponds to 0.04 ± 0.01 Ξ- per event in the transverse momentum range pt>1.0 GeV/c and in the pseudorapidity range
