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.

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.
