We report the preliminary measurement by the FOCUS Collaboration (E831 at Fermilab) of masses and widths of the L=1 charm mesons D*0_2 and D*+_2. The fit of the invariant mass distribution requires an additional term to account for a broad structure over background.

Abstract

We report the preliminary measurement by the FOCUS Collaboration (E831 at Fermilab) of masses and widths of the L=1 charm mesons D*0_2 and D*+_2. The fit of the invariant mass distribution requires an additional term to account for a broad structure over background.
