Abstract

We follow on the steps of the LHCb collaboration which first discovered five excited states of baryons with strangeness and charm, Ωc0, in pp collisions, by discussing the Ω− →πΞc+K−decay, a process which has been recently studied by the same collaboration obtaining four narrow Ωc0 states compatible with the previously found ones. We explore these new found states from a hadronic molecular viewpoint and find that two out of the four resonances, Ωc(3050)0 and Ωc(3090)0, might be interpreted as pentaquark states, structured as meson-baryon bound molecules.
