Hidden-charm pentaquarks with triple strangeness due to the Ωc(*) (D)over-bars(*) interactions

Motivated by the successful interpretation of these observed P-c and P-cs states under the meson-baryon molecular picture, we systematically investigate the possible hidden-charm molecular pentaquark states with triple strangeness which is due to the Omega(()(c)*()) (D) over bar (()(s)*()) interactions. We perform a dynamical calculation of the possible hidden-charm molecular pentaquarks with triple strangeness by the one-boson-exchange model, where the S-D wave mixing effect and the coupled channel effect are taken into account in our calculation. Our results suggest that the Omega(c)(D) over bar (s)*state with J(P) = 3/2(-) and the Omega(c)*(D) over bar (s)* state with J(P) = 5/2(-) can be recommended as the candidates of the hidden-charm molecular pentaquark with triple strangeness. Furthermore, we discuss the two-body hidden-charm strong decay behaviors of these possible hidden-charm molecular pentaquarks with triple strangeness by adopting the quark-interchange model. These predictions are expected to be tested at the LHCb, which can be a potential research issue with more accumulated experimental data in near future.

Automated summary

In this study, we systematically investigate the possible hidden-charm molecular pentaquark states with triple strangeness and propose Omega(c)(D) over bar(s)* state and Omega(c)*(D) over bar(s)* state as candidates for the hidden-charm molecular pentaquark with triple strangeness. The decay behaviors of these states are discussed using the quark-interchange model, with expectations for validation at LHCb with more experimental data.
