We report measurements of the resonance properties of
Lambda+(c)(2595)+ and Lambda+(c)(2625)+ baryons in their decays to
Lambda+_c pi++ pi+- as well as Sigma_c(2455)++,0 and Sigma_c(2520)++,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 p anti-p collisions at s**(1/2) ñ.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.
