Query: $\boldsymbol{\Omega_b^- \to (\Xi_c^+ \, K^-) \, \pi^-}$ and the
  $\boldsymbol{\Omega_c}$ states   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.
