Abstract

We report new precision measurements of the lifetimes of the

Λ_{c}^{+}

and

D^{0}

from SELEX, the charm hadroproduction experiment at Fermilab. Based upon 1630

Λ_{c}^{+}

and 10 210

D^{0}

decays we observe lifetimes of

τ [Λ_{c}^{+}] = 198.1 \pm 7.0 \pm 5.6 fs

and

τ [D^{0}] = 407.9 \pm 6.0 \pm 4.3 fs

.
