We report precise measurements of the D0 and D+ meson lifetimes by the E687 Collaboration at Fermilab. The measurements have been made using 16000 fully reconstructed decays of the D0 into the K−pi+ and K−pi+pi−pi+ final states and 9000 decays of the D+ into the K−pi+pi+ final state. The lifetimes of the D0 and D+ mesons are measured to be 0.413±0.004±0.003 ps and 1.048±0.015±01011 ps respectively.

Abstract

We report precise measurements of the D0 and D+ meson lifetimes by the E687 Collaboration at Fermilab. The measurements have been made using 16000 fully reconstructed decays of the D0 into the K−pi+ and K−pi+pi−pi+ final states and 9000 decays of the D+ into the K−pi+pi+ final state. The lifetimes of the D0 and D+ mesons are measured to be 0.413±0.004±0.003 ps and 1.048±0.015±01011 ps respectively.
