摘要

We study the S-wave DΞ bound state in the Bethe–Salpeter formalism in the ladder and instantaneous approximations. With the kernel generated by the hadronic effective Lagrangian, two open-charmed bound states, which quantum numbers are I= 0 , JP=(12)- and I= 1 , JP=(12)-, respectively, are predicted as new candidates of hadronic pentaquark molecules in our formalism. If existing, they could contribute to the broad 3188 MeV structure near the five new narrow Ω_c states observed recently by the LHCb Collaboration.
