Abstract
We report on precision measurements of the masses and widths of the narrow, orbitally excited states D-1(0) and D-2(*0) using the CDF II detector at the Fermilab Tevatron. Both states (collectively called D-**) are reconstructed in the decay channel D-**-> D*+pi(-). The D-2(*0) is also reconstructed in the D-**-> D+pi(-) channel. Using a data set with an integrated luminosity of 210 pb(-1), the measured masses and widths for the D-1(0) are 2421.7 +/- 0.7 +/- 0.6 MeV/c(2) and 20.0 +/- 1.7 +/- 1.3 MeV/c(2) respectively, while for the D-2(*0) they are 2463.3 +/- 0.6 +/- 0.8 MeV/c(2) and 49.2 +/- 2.3 +/- 1.2 MeV/c(2). These values are currently the single best measurements available.
