Abstract

Using data recorded by the CLEO-II detector at CESR, we report evidence of a pair of excited charmed baryons, one decaying into λ⁺_cπ⁺and the other into λ⁺_cπ^-. The doubly charged state has a measured mass difference M(λ⁺_cπ⁺)- M(λ⁺_c) of 234.5 ± 1.1 ± 0.8 MeV/c²and a width of 17.9^+3.8_-3.2± 4.0 MeV/c², and the neutral state has a measured mass difference M (λ⁺_cπ⁺)-M (λ⁺_c) of 232.6 ± 1.0 ± 0.8 MeV/c²and a width of 13.0_-3.0^+3.7± 4.0 MeV/c². We interpret these data as evidence of the Σ^*++_cand Σ^*0_cthe spin 3/2⁺excitations of the Σ_cbaryons.

N2 - Using data recorded by the CLEO-II detector at CESR, we report evidence of a pair of excited charmed baryons, one decaying into λ+cπ+and the other into λ+cπ-. The doubly charged state has a measured mass difference M(λ+cπ+)- M(λ+c) of 234.5 ± 1.1 ± 0.8 MeV/c2and a width of 17.9+3.8-3.2± 4.0 MeV/c2, and the neutral state has a measured mass difference M (λ+cπ+)-M (λ+c) of 232.6 ± 1.0 ± 0.8 MeV/c2and a width of 13.0-3.0+3.7± 4.0 MeV/c2. We interpret these data as evidence of the Σ*++cand Σ*0cthe spin 3/2+excitations of the Σcbaryons.
