Measurement of Charm Meson Lifetimes
Measurement of Charm Meson Lifetimes
We report measurements of the $D^0, D^+$, and $D^+_s$ meson lifetimes using $3.7 fb^{-1}$ of e^+e^- annihilation data collected near the $\Upsilon(4S)$ resonance with the CLEO detector. The lifetimes of the $D^0, D^+$, and $D^+_s$ mesons are measured to be $408.5 \pm 4.1 ^{+3.5}_{-3.4} fs, 1033.6 \pm 22.1 ^{+9.9}_{-12.7} fs$, …
