Overview

abstract

• In 2002, the SELEX [1] Experiment (Fermilab E781) reported the first observation of a member of the family of doubly charmed baryons [2]. During the last two years, additional evidence for more members of that family has been obtained and will be presented. SELEX took data in 1996/7 in the Fermilab PCenter beam line, observing interactions of Σ-, pions and protons with momenta of about 600 GeV/c on copper and diamond target foils. From about 15 · 10 9 live interactions the trigger and online filter system selected 109 events which were written to tape. SELEX [9] features a high resolution Silicon Microstrip Vertex detector, a Photomultiplier RICH detector [10] for particle identification, and a 3-stage electromagnetic calorimeter. © 2005 Elsevier B.V.
