摘要：

Using data recorded by the CLEO II and CLEO II.V detector configurations at CESR, we report new measurements of the masses of the Sigma(c)(++) and Sigma(c)(0) charmed baryons, and the first measurements of their intrinsic widths. We find M(Sigma(c)(++))-M(Lambda(c)(+))=167.4+/-0.1+/-0.2 MeV, Gamma(Sigma(c)(++))=2.3+/-0.2+/-0.3 MeV, and M(Sigma(c)(0))-M(Lambda(c)(+))=167.2+/-0.1+/-0.2 MeV, Gamma(Sigma(c)(0))=2.5+/-0.2+/-0.3 MeV, where the uncertainties are statistical and systematic, respectively.
