Abstract

In an experiment measuring charmed-particle lifetimes with use of a hybrid-emulsion spectrometer in the wide-band neutrino beam at the Fermi National Accelerator Laboratory, 1248 neutrino and antineutrino interactions have been located. Twenty-three charged charm decay candidates have been reconstructed, from which we determine the lifetime of the D± to be 11.5-3.5+7. 5 × 10-3 s, that of the F± to be 1.9-0. 7+1. 3 × 10-13 s, and that of the Λc+ to be 2.3-0. 6+1. 0 × 10-13 s.
