Abstract
We report on the first direct observation of a neutrino induced charge d-current interaction with two subsequent decays of short-lived partic les close to the interaction vertex. This rare double-kink signature i n the CHORUS emulsion target is interpreted as a D-s(+) production fo llowed by the decay chain D-s(+) --> D-s(+) gamma, D-s(+) --> tau(+) v(tau),tau(+) --> mu(+) v(mu)v(tau). The event is characterised by sma ll Q(2) and small four-momentum transfer squared t to the target nucle on, which indicates a diffractive production mechanism. A complete ana lysis of the event is presented. (C) 1998 Elsevier Science B.V. All ri ghts reserved.
