摘要：

Using data recorded by the CLEO III detector at the Cornell electron storage ring (CESR), we have made measurements of some properties of the Sigma(*)(++)(c) and Sigma(*)(0)(c) charmed baryons. In particular: Gamma(Sigma(*)(++)(c)) = 14.4-1.5+1.6 +/- 1.4 MeV, M(Sigma(*)(++)(c)) - M(Lambda(+)(c)) = 231.5 +/- 0.4 +/- 0.3 MeV, Gamma(Sigma(*0)(c)) = 16.6-1.7+1.9 +/- 1.4 MeV, M(Sigma(*0)(c)) - M(Lambda(+)(c)) = 231.4 +/- 0.5 +/- 0.3 MeV.
