Book Description

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?{sub c} baryon, the resonances?{sub c}(2595) and?{sub c}(2625), in the decay channel?{sub c}?+?−, as well as the?{sub c} spin excitations?{sub c}(2455) and?{sub c}(2520) in its decays to?{sub c}+?− and?{sub c}+?− 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?{sub c} and the decay widths of these states, using significantly higher statistics than previous experiments.
