Abstract
We report measurements of the resonance properties of Lambdac(2595)+ and Lambdac(2625)+ baryons in their decays to Lambdac+pi+- as well as Sigmac(2455)++,0 and Sigmac(2520)++,0 baryons in their decays to Lambdac+pi± final states. These measurements are performed using data corresponding to 5.2 f[superscript -1] of integrated luminosity from pp[over-bar] collisions at [sqrt]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 Sigmac states, and significantly smaller uncertainties than the world averages for excited Λc+ states.
