Abstract

From the analysis of 685 neutrino and antineutrino interactions in an emulsion target, fifteen candidates for the multiprong decay of charged charmed particles are found. This Letter presents lifetimes for the ${D}^{\ifmmode\pm\else\textpm\fi{}}$, ${F}^{\ifmmode\pm\else\textpm\fi{}}$, and ${{\ensuremath{\Lambda}}_{c}}^{+}$ states based on the fitted events of the sample.
