Recent results from neutrino interactions in heavy neon
Recent results presented from a study of muon neutrinos interacting in heavy neon include dilepton production, strange particle rates, the D/sup 0/..-->..K/sup 0/..pi../sup +/..pi../sup -/ decay, the lack of observation of new particles, and the cross section for nu/sub e/ + e elastic scattering. 8 references (JFP

Observation of a visible charmed particle decay in neutrino interactions
In a sample of 250 semileptonic charmed particle decays (..nu../sub ..mu../ + Neon ..-->.. ..mu../sup -/ + e/sup +/ + ... events), one clear event is found where the e/sup +/ does not come directly from the ..nu.. interaction vertex but from a decay point 1.1 cm downstream of the vertex. This event is interpreted as a visible charmed particle decay: into an e/sup +/ and a positive and a negative charged track. The observation of a visible charm decay in the sample is consistent with what is expected if the charm lifetime were of the order 5 x 10/sup -13/ sec. 5 references
