Abstract
We report final results for the ${D}^{0}$ lifetime measured with a hybrid emulsion spectrometer in the wide-band neutrino beam at Fermilab. In a total of 3886 neutrino and antineutrino interactions located in the emulsion fiducial volume, we have found 58 ${D}^{0}$ decays, from which we determine the lifetime to be (${4.3}_{\ensuremath{-}0.5\ensuremath{-}0.2}^{+0.7+0.1}$) \ifmmode\times\else\texttimes\fi{} ${10}^{\ensuremath{-}13}$ s.
