Abstract

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