Results from the WA92 experiment

The report on a search for beauty particles produced in π−-nucleon interactions at s ≃ 26 GeV at the CERN Ω′ spectrometer. Data were collected using the WA92 apparatus, which included a high-resolution imaging detector and a system for triggering on secondary vertices. The search for beauty decays using conventional analysis procedures is described and a new event-selection method, based on neural-network techniques, is presented. Results obtained with the new and the conventional methods are compared.
