dc.description.abstractThe recently observed strange pentaquark candidate, PΛψs(4338)0, is investigated to provide information about its nature and substructure. To this end, its mass and width through the decay channels PΛψs(4338)0→J/ψΛ and PΛψs(4338)0→ηcΛ are calculated by applying two- and three-point QCD sum rules, respectively. The state is considered as a Ξc¯D meson-baryon molecular structure with spin-parity quantum numbers JP=12−. The obtained mass, mPΛψs(4338)0=4338±130  MeV, and width, ΓPΛψs(4338)0=10.40±1.93  MeV, are consistent with the experimental data within the presented uncertainties. This allows us to assign a Ξc¯D molecular structure of JP=12− for the PΛψs(4338)0 state.
