Query: The molecular nature of some $\Omega_c^0$ states   A vector meson exchange model based on effective Lagrangians is used to build
the meson--baryon interaction in the charm $+1$, strangeness $-2$ and isospin
$0$ sector. The s-wave scattering amplitudes resulting from the unitarization
in coupled-channels show two resonances with masses and widths that are in very
good agreement with those of the experimental $\Omega_c(3050)^0$ and
$\Omega_c(3090)^0$ states observed by the LHCb collaboration. The
interpretation of these resonances as pseudoscalar meson--baryon molecules
would mean the assignment $J^P=1/2^-$ to their spin--parity.
