Description
The spectrum of hyperon with S=-2,-3 are still not well known.
The large data sample accumulated by the Belle experiment at KEKB asymmetric energy $e^+ e^-$ collider provide
a unique opportunity to study these hyperons.
In this presentation, we report observation and evidence of $\Xi(1620)$ and $\Xi(1690)$ in the $\Xi_c \to \Xi\pi\pi$ decay,
and observation of new excited Omega- baryon decaying into Xi K produced from bottomonium decay.
