Résumé : A search for direct evidence of the production and subsequent decay of gluinos has been performed in nuclear emulsions. The emulsion stacks were exposed, as part of a large hybrid apparatus, to a beam of 350GeV/cπt- mesons, and events were selected on the basis of a "missing-energy" trigger. The missing-energy signature is expected to be a characteristic feature of events in which gluinos are produced and subsequently decay into hadrons and almost non-interacting photinos. The negative result of this search sets an upper limit to the production cross section of light gluinos. © 1987.
