Due to an excellent mass resolution and a large amount of available data, the CDF experiment, located at the Tevatron proton-antiproton accelerator, allows the precise measurement of spectroscopic properties, like mass and decay width, of a variety of states. This was exploited to examine the first orbital excitations of the Λc baryon, the resonances Λc(2595) and Λc(2625), in the decay channel [Formula: see text], as well as the Λc spin excitations Σc(2455) and Σc(2520) in its decays to [Formula: see text] and [Formula: see text] final states in a data sample corresponding to an integrated luminosity of 5.2 fb-1. We present measurements of the mass differences with respect to the Λc and the decay widths of these states, using significantly higher statistics than previous experiments.
