This work predicts the mass spectra of doubly charmed molecular pentaquark candidates and identifies the most promising ones. The radiative decays and magnetic moments of these candidates are also investigated. The authors suggest that the LHCb Collaboration should focus on searching for these candidates in the coming years.
In this work, we first predict the mass spectra of the Omega((*))(C) D-S((*))-type doubly charmed molecular pentaquark candidates, where the one-boson-exchange model is adopted by considering both the S-D wave mixing effect and the coupled channel effect. Our findings indicate that the Omega D-C(S)* state with J(P) = 1/2(-), the Omega D-*(C)S(*) state with J(P) = 1/2(-), and the Omega D-*(C)S(*) state with J(P) = 3/2(-) can be considered as the most promising doubly charmed molecular pentaquark candidates, and the Omega D-C(S) state with J(P) = 1/2(-), the Omega D-*(C)S state with J(P) = 3/2(-), and the Omega D-C(S)* state with J(P) = 3/2(-) are the possible doubly charmed molecular pentaquark candidates. Furthermore, we further explore the radiative decays and the magnetic moments of the most promising doubly charmed molecular pentaquark candidates in the constituent quark model. As a crucial aspect of spectroscopy, the information of the radiative decays and the magnetic moments can provide the valuable clues to reflect their inner structures. With the accumulation of higher statistical data at the Large Hadron Collider, we propose that the LHCb Collaboration should focus on the problem of searching for these predicted doubly charmed molecular pentaquark candidates containing most strange quarks in the coming years.
