Search forD/emph>production in pion-nucleon interactions

Results are presented of a measurement of the production of $D^{\mathrm{*}+}$ ($D^{\mathrm{*}\mathrm{-}}$) in 250-GeV/c ${\pi }^{\mathrm{-}}$N interactions. We observe 2.1±7.8 events corresponding to a charge-$D^{\mathrm{*}}$ cross section σ($D^{\mathrm{*}}$) of 0.4±1.5 μb/nucleon. When averaged with our previous measurement made at 200 GeV/c, the result is σ($D^{\mathrm{*}}$)=2.3±1.0 μb/nucleon with (dσ/dx)${\Vert }_{x=0\mathrm{}}$=4.6±2.0 μb.
