Abstract
- We report precise measurements of the D 0 and D + meson lifetimes by the E687 Collaboration at Fermilab. The measurements have been made using 16000 fully reconstructed decays of the D 0 into the K − π + and K − π + π − π + final states and 9000 decays of the D + into the K − π + π + final state. The lifetimes of the D 0 and D + mesons are measured to be 0.413±0.004±0.003 ps and 1.048±0.015±01011 ps respectively.
