Measurement of mass and width of the excited charmed meson states D10 and D2*0 at CDF

Abstract:

We report on precision measurements of the masses and widths of the narrow, orbitally excited states D10 and D2*0 using the CDF II detector at the Fermilab Tevatron. Both states (collectively called D**) are reconstructed in the decay channel D**→D*+π-. The D2*0 is also reconstructed in the D**→D+π- channel. Using a data set with an integrated luminosity of 210pb-1, the measured masses and widths for the D10 are 2421.7±0.7±0.6 MeV/c2 and 20.0±1.7±1.3 MeV/c2 respectively, while for the D2*0 th...
