Abstract

We study the possibility that some of the four peaks recently observed in the Ξ K− mass spectrum by the LHCb collaboration, or the other four non statistically significant peaks in the higher energy region, could correspond to states with five quarks, structured as meson-baryon molecules. These states emerge from a unitarized s-wave amplitude obtained from an appropriate effective meson-baryon Lagrangian. To confirm that some of these states are of molecular origin, more statistics would be needed in that energy region.
