Özet

We report on a search for associated charm production in neutrino charged-current interactions in the CHORUS experiment, based on the visual observation of charmed-particle decays. The search differs from those carried out so far in which the production of c (c) over bar has been inferred from measurements of events with two or three nations in the final state, resulting from the decay of charmed hadrons. One event with a double charm-decay topology has been found and a corresponding background of 0.04 events has been evaluated. (C) 2002 Elsevier Science B.V. All rights reserved.
