The mass of the [Lambda]c(2625)+, relative to the [Lambda]+c mass, is already relatively well known, but the large Belle data sample allows for a more precise measurement. No intrinsic width of the [Lambda]c(2625)+ has yet been measured, and the current upper limit [Gamma]

We report measurements of the resonance properties of [Lambda]c(2595)+ and [Lambda]c(2595)+ baryons in their decays to [Lambda]c+[pi]+[pi]- as well as [Sigma]c(2455)++,0 and [Sigma]c(2455)++,0 baryons in their decays to [Lambda]c+[pi]± final states. These measurements are performed using data corresponding to 5.2 fb-1 of integrated luminosity from pp̄ collisions at √s = 1.96 TeV, collected with the CDF II detector at the Fermilab Tevatron. Exploiting the largest available charmed baryon sample, we measure masses and decay widths with uncertainties comparable to the world averages for [Sigma]c states, and significantly smaller uncertainties than the world averages for excited [Lambda]c+ states.
