Abstract

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