Abstract

In this work, we analyze the strong vertices of hadronic molecules DK, D^*K, DK^* and their bottom analogs within the framework of three-point QCD sum rules. The coupling between interpolating currents and low spin particles is considered in the phenomenological side, and the vacuum condensates ⟨ qq ⟩ ,⟨ g_s²GG ⟩ ,⟨ qg_sσGq ⟩ ,⟨ g_s³GGG ⟩ ,⟨ qq ⟩ ² are included in the QCD side. As an application of strong coupling constants, we also obtain the partial decay widths of these states, where Γ_T_DK→ D_sπ=10.3_-2.9^+3.0KeV, Γ_T_D^*K→ D_s^*π=24.8_-5.4^+5.5KeV, Γ_T_BK→ BK=101_-21⁺³⁶MeV and Γ_T_B^*K→ B^*K=142_-25⁺⁵²MeV. It is shown that the results of Γ_T_DK→ D_sπ and Γ_T_D^*K→ D_s^*π are compatible with the experimental data of D_s0^*(2317) and D_s1(2460).
