Preliminary Results on Charmed Meson Spectroscopy

Abstract

We report the preliminary measurement by the FOCUS Collaboration (E831 at Fermilab) of masses and widths of the L=1 charm mesons $D_2^{\ast 0}$ and $D_2^{\ast +}$. The fit of the invariant mass distribution requires an additional term to account for a broad structure over background.
