Description
The $\Xi$ excited states are not well understood because of less experimental study. In this presentation, we report on the studies of $\Xi(1620)^0$ and $\Xi(1690)^0$ via the $\Xi_c^+ -> \Xi^- \pi^+ \pi^+$ decays by using a data sample collected with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. We observe the $\Xi(1620)^0$ and measure its mass and width. We find an evidence of the $\Xi(1690)^0$ in the $\Xi\pi$ decay mode.
