Abstract
We report new precision measurements of the lifetimes of the A(c)(+) and D- 0 from SELEX, the charm hadroproduction experiment at Fermilab. Based upon 1630 A(c)(+) and 10210 D-0 decays we observe lifetimes of tau [A(c)(+)] = 1 98.1 +/- 7.0 +/- 5.6 fs and tau [D-0] = 407.9 +/- 6.0 +/- 4.3 fs.
