Abstract

We report the first observation of two narrow charmed strange baryons decaying to Ξ⁺ _cγ and Ξ⁰ _Cγ, respectively, using data from the CLEO II detector at the Cornell Electron Storage Ring. We interpret the observed signals as the Ξ^+′ _c(c(u)) and Ξ^0′ _cγ(c(sd)), the symmetric partners of the well-established antisymmetric Ξ⁺ _c(c[su]) and Ξ⁰ _c(c[sd]). The mass differences M(Ξ^+′ _c)-M(Ξ⁺ _c) and M(Ξ^0′ _c)-M(Ξ⁰ _c) have been measured to be 107.8±1.7±2.5 and 107.0±1.4±2.5MeV/c², respectively.
