Abstract
We have investigated D+pi- and D+pi-final states and observed the two established L = 1 charmed mesons, the D1 (2420)0 with mass 2421(-2-2) +1+2 MeV/c2 and width 20(-5-3)(+6+3) MeV/c2 and the D2(2460)0 with ma ss 2465 +/- 3 +/- 3 MeV/c2 and width 28(-7-6)+8+6 MeV/c2. Properties o f these final states, including their decay angular distributions and spin-parity assignments, have been studied. We identify these two meso ns as the j(light) = 3/2 doublet predicted by HQET. We also obtain con straints on GAMMA(s)/(GAMMA(s) + GAMMA(D)) as a function of the cosine of the relative phase of the two amplitudes in the D1(2420)0 decays.
