Abstract
We report measurements of the resonance properties of Λ c(2595)+ and Λc(2625)+ baryons in their decays to Λc+π+π- as well as Σc(2455)++,0 and Σ c(2520)++,0 baryons in their decays to Λc+π± final states. These measurements are performed using data corresponding to 5.2fb-1 of integrated luminosity from pp̄ collisions at √s=1.96TeV, 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 Σc states, and significantly smaller uncertainties than the world averages for excited Λc+ states. © 2011 American Physical Society.
