In this work, heavy-strange meson systems were systematically investigated to study possible molecules using a quasipotential Bethe-Salpter equation approach and one-boson exchange model. Molecular states were found and their relationships were explored, shedding light on the internal structure of various heavy-strange mesons.
In this work, we systematically investigate the heavy-strange meson systems, D(*)(K*)/(B) over bar(*)(K*) and (D) over bar(*)(K*)/B(*)(K*), to study possible molecules in a quasipotenial Bethe-Salpter equation approach together with the one-boson exchange model. The potential is achieved with the help of the hidden-gauge Lagrangians. Molecular states are found from all six S-wave isoscalar interactions of D(*)(K*) or (B) over bar(*)(K*). The charmed-strange mesons D*(s0) (2317) and D-s1(2460) can be related to the DK and D*K states with spin parities 0(+) and 1(+), respectively. In the current model, the (B) over barK* molecular state with 1(+) is the best candidate of the recent observed B-sJ(6158). Four molecular states are produced from the interactions of (D) over bar(*)K(*) or B(*)K(*). The relation between the (D) over barK* molecular state with 0(+) and the X-0(2900) is also discussed. No isovector molecular states are found from the interactions considered. The current results are helpful to understand the internal structure of D*(s0)(2317), D-s1(2460), X-0(2900), and new B-sJ states. The experimental research for more heavy-strange meson molecules is suggested.
