${\mathbf{\Omega }}_{\mathbf{b}}^{-}\to ({\mathbf{\Xi }}_{\mathbf{c}}^{+}{\mathbf{K}}^{-}){\mathbf{\pi }}^{-}$ and the ${\mathbf{\Omega }}_{\mathbf{c}}$ states

Abstract

We study the weak decay ${\Omega }_b^{-}\to ({\Xi }_c^{+}{K}^{-}){\pi }^{-}$, in view of the narrow ${\Omega }_c$ states recently measured by the LHCb collaboration and later confirmed by the Belle collaboration. The ${\Omega }_c(3050)$ and ${\Omega }_c(3090)$ are described as meson-baryon molecular states, using an extension of the local hidden gauge approach in coupled channels. We investigate the $\Xi D$, ${\Xi }_c\bar{K}$ and ${\Xi }_c^{\prime }\bar{K}$ invariant mass distributions making predictions that could be confronted with future experiments, providing useful information that could help determine the quantum numbers and nature of these states.
