[D10.004] Observation of the production of charmed baryons \Sigma_c^\circ and\$\Sigma_c^++ in p\barp collisions at \sqrts=1.96~ TeV

Dmitri Naumov (University of New Mexico)

We report on the observation of charmed baryon states \Sigma_c^\circ and \Sigma_c^++ decaying strongly into \Lambda_c^+ \pi^- and \Lambda_c^+ \pi^+, respectively, where the \Lambda_c^+ state is reconstructed in the p K^- \pi^+ mode. The analysis is based on data collected so far with the CDF-II detector.
