description

We observe that four peaks seen in the high energy part of the $\Omega_b$ spectrum of the recent LHCb experiment are in remarkable agreement with predictions made for molecular $\Omega_b$ states stemming from the meson-baryon interaction, with an approach that applied to the $\Omega_c$ states gave rise to three states in good agreement with experiment in masses and widths. While the statistical significance of the peaks prevents us from claims of states at the present time, the agreement found should be an incentive to look at this experiment with increased statistics to give an answer to this suggestive idea.
