Abstract
We report the first observation of the double strange baryon in its decay to via decays based on a data sample collected with the Belle detector at the KEKB asymmetric-energy collider. The mass and width are measured to be and , respectively. We obtain evidence of the with the same data sample. These results shed light on the structure of hyperon resonances with strangeness .
