Abstract
We report the measurement of masses and widths of the following L = 1 charm mesons by the E687 Collaboration at Fermilab: a D20 state of ma ss (width) 2453 +/- 3 +/- 2 (25 +/- 10 +/- 5) MeV/c2 decaying to D+pi- , a D2+ state of mass (width) 2453 +/- 3 +/- 2 (23 +/- 9 +/- 5) MeV/c 2 decaying to D0pi+, a D1(0) state of mass (width) 2422 +/- 2 +/- 2 (1 5 +/- 8 +/- 4) MeV/c2 decaying to D+pi-, and a D(s1)+ state of mass 2 535.0 +/- 0.6 +/- 1.0 MeV/c2 and width < 3.2 MeV/c2 at 90% confidence level, decaying to D+K(s)0 and D*0K+.
