Systematical study of Ωc-like molecular states from interactions Ξc(,*)K¯(*) and Ξ(*)D(*)

open access: yesPhysical Review, 2022
In this work, the Ωc-like molecular states are systematically investigated in a quasipotential Bethe-Salpeter equation approach. The relevant interactions Ξc(*,′)K¯(*), Ξ(*)D(*), and Ωc(*)(π/η/ρ/ω) are described by light meson exchanges with the help of the effective Lagrangians with SU(3), chiral, and heavy quark symmetries.
