Key Points

This research aims to measure the masses and widths of the charm mesons D^+_2 and D^+_2 to understand their properties better.
Conducted measurements at Fermilab by the FOCUS collaboration (E831)
Analyzed the invariant mass distribution of charm mesons
Used fitting techniques to identify mass and width characteristics
Identified masses and widths of D^+_2 mesons
Found a need for an additional term in the fit to explain broad structures over the background
Suggested implications for our understanding of particle states

Implication

FOCUS collaboration measures charmed meson properties, suggesting new insights into particle physics.

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 and D*^+_2 . The fit of the invariant mass distribution requires an additional term to account for a broad structure over background.
