Abstract

In an experiment measuring charmed-particle lifetimes with a hybrid emulsion spectrometer, 1248 neutrino and antineutrino interactions produced by the wide-band beam at Fermi National Accelerator Laboratory have been located. Twenty-one candidates for the decay of neutral charmed particles are found. The lifetime for the D0 based on the sixteen constrained events of this sample is measured to be 2.3-0.5+0.8×10-13 sec.
