Abstract

Using data recorded by the CLEO II detector at the Cornell Electron Storage Ring, we report evidence for two new charmed baryons, one decaying into Ξ⁺_cπ⁺π⁻ via an intermediate Ξ^*0_c and its isospin partner decaying into Ξ⁰_cπ⁺π⁻ via an intermediate Ξ^*+_c. We measure the mass differences of the two states to be M(Ξ⁺_cπ⁺π⁻)−M(Ξ⁺_c)=348.6±0.6±1.0 MeV, and M(Ξ⁰_cπ⁺π⁻)− M(Ξ⁰_c)=347.2±0.7±2.0 MeV. We interpret these new states as the J^P = 3/2⁻ Ξ_c1 particles, the charmed-strange analogs of the Λ⁺_c1(2625).
