Abstract

We report measurement of the decays of the $\Omega_c^0$ charmed baryon into hadronic final states and observe excited $\Omega_c^*$ charmed baryons in the decay mode $\Xi_c^+K^-$ including $\Omega_c(3000)$, $\Omega_c(3050)$, $\Omega_c(3066)$ and $\Omega_c(3090)$. In addition, we report the first observation of the $\Xi_c(2930)^0$ charmed-strange baryon with a significance greater than $5\sigma$ in its decay to $K^-\Lambda_c^+$ in $B^-\to K^-\Lambda_c^+\bar\Lambda_c^-$ decays. The branching fractions of the decays $\Lambda_c^+\to\Sigma^+\pi^-\pi^+$, $\Lambda_c^+\to\Sigma^+\pi^+\pi^0$ and $\Lambda_c^+\to\Sigma^+\pi^0\pi^0$ are also measured.
The analyses are based on a data set recorded by the Belle detector from $e^+e^-$ collisions produced by the KEKB collider.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating very compact bibliographies which can be beneficial to authors and readers, and in "proceeding" format which is more detailed and complete.
