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*0c and its isospin partner decaying into Ξ0cπ+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(Ξ0cπ+π)− M(Ξ0c)=347.2±0.7±2.0 MeV. We interpret these new states as the JP = 3/2 Ξc1 particles, the charmed-strange analogs of the Λ+c1(2625).

N2 - 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*0c and its isospin partner decaying into Ξ0cπ+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(Ξ0cπ+π−)− M(Ξ0c)=347.2±0.7±2.0 MeV. We interpret these new states as the JP = 3/2− Ξc1 particles, the charmed-strange analogs of the Λ+c1(2625).
