Abstract

We report the measurement of masses and widths of the following L=1 charm mesons by the E687 Collaboration at Fermilab: a D2*0 state of mass (width) 2453±3±2 (25±10±5) MeV/c2 decaying to D+π-, a D2*+ state of mass (width) 2453±3±2 (23±9±5) MeV/c2 decaying to D0π+, a D10 state of mass (width) 2422±2±2 (15±8±4) MeV/c2 decaying to D*+π-, and a Ds1+ state of mass 2535.0±0.6±1.0 MeV/c2 and width <3.2 MeV/c2 at 90% confidence level, decaying to D*+Ks0 and D*0K+.
