Abstract:$D\sp{\pm}$ mesons have been observed in photoproduction in Fermilab experiment E687. A sample of approximately 2500 events of the decay $D\sp{\pm}\ \to\ K\sp{\pm}\pi\sp{\pm}\pi\sp{\pm}$ has been analyzed. The cross section for $x\sb{f}\ >$ 0 is measured to be BR $\cdot$ $\sigma$ = 0.368 $\pm$ 0.073 $\pm$ 0.111 $\mu$b/Be nucleus at our average photon energy of 220 GeV. The cross section dependence on incident photon energy, Feynman x, and transverse momentum has also been measured and found to be in good agreement with other measurements.
The lifetime of the $D\sp{\pm}$ has been measured to be 1.061 $\pm$ 0.039 $\pm$ 0.020 picoseconds. This measurement is also in good agreement with recent results.
