Abstract

We report final results for the D±, F±, and Λc+ lifetimes measured with a hybrid emulsion spectrometer in the wide-band neutrino beam at Fermilab. In total, 3886 neutrino and antineutrino interactions were located in the fiducial volume of the emulsion. From these interactions we have unambiguously identified 6 F± and 13 Λc+ decays, for which the fitted lifetimes are τ(F±)=(2.6−0.9+1.6)×10−13 s and τ(Λc+)=(2.0−0.5+0.7)×10−13 s. 28 other decays are consistent with a D+ or D− hypothesis. From these events, we obtain a D± lifetime of (11.1−2.9+4.4) × 10−13s.
