Abstract The DK interaction is relevant to the interpretation of the DsJ(2317). We dynamically investigate S-wave DK interactions in the chiral SU(3) quark model by solving the resonating group method equation. The numerical results show an attraction between D and K, which is from boson exchanges between light quarks. However, such an attraction is not strong enough to form a DK molecule. Meanwhile, S partial wave phase shifts of DK elastic scattering are obtained. The case of S-wave D*K is rather similar to that of DK. To draw a definite conclusion of whether a molecular state exists in DK or the D*K system, more details of dynamics should be considered in a future study.
