Doubly charmed pentaquark states with strangeness $S=0,-1$

In this work, we have studied the mass spectra of doubly charmed pentaquark states with strangeness $S=0,-1$ by using the method of QCD sum rules. We use the parity projected sum rules to separate the contributions of negative and positive parities from the two-point correlation functions induced by the pentaquark interpolating currents. Our results predict the existence of some potential doubly charmed pentaquark bound states.
