Abstract
We report the first observation of two charmed strange baryons that decay into Λc+K-π+. The broader of the two states is measured to have a mass of 2978.5±2.1±2.0MeV/c2 and a width of 43.5±7.5±7. 0MeV/c2. The mass and width of the narrow state are measured to be 3076.7±0.9±0.5MeV/c2 and 6.2±1.2±0.8MeV/c2, respectively. We also perform a search for the isospin partner states that decay into Λc+KS0π- and observe a significant signal at the mass of 3082.8±1.8±1.5MeV/c2. The data used for this analysis were accumulated at or near the Υ(4S) resonance, using the Belle detector at the e+e- asymmetric-energy collider KEKB. The integrated luminosity of the data sample used is 461.5fb-1.

N2 - We report the first observation of two charmed strange baryons that decay into Λc+K-π+. The broader of the two states is measured to have a mass of 2978.5±2.1±2.0MeV/c2 and a width of 43.5±7.5±7. 0MeV/c2. The mass and width of the narrow state are measured to be 3076.7±0.9±0.5MeV/c2 and 6.2±1.2±0.8MeV/c2, respectively. We also perform a search for the isospin partner states that decay into Λc+KS0π- and observe a significant signal at the mass of 3082.8±1.8±1.5MeV/c2. The data used for this analysis were accumulated at or near the Υ(4S) resonance, using the Belle detector at the e+e- asymmetric-energy collider KEKB. The integrated luminosity of the data sample used is 461.5fb-1.
